Introduction
As the title says, this guide aims to be your one stop shop for all the details you could ever need on your adorable little fishes if (like myself) you want to get into the nitty-gritty details of animal care. Most of this information has been pulled from in-game and the wiki, and personally I'm not a fan of how the game organizes your animals, even after the additional filters that have been added. As such, I aim to make this guide, and finding the information within it, as simple and intuitive as possible.

This guide starts off with several sections on the icons that you will find in the animal information boxes and an alphabetized list of all the animals in the game. The bulk of this guide sorts every single animal in the game by Rank and gives all of their data for your convenience. I have also included my personal recommendations for which animals should be paired up with who, mainly judged by shared food type and skill levels. Feel free to ignore these, as they are completely subjective.

All data has been taken from Normal difficulty. This guide covers the base game, for the Freshwater Frenzy or Architect's Collection animals, check out my other guides at The Ultimate Animal Guide (Freshwater Frenzy), The Ultimate Animal Guide (Architect's Collection) and The Ultimate Animal Guide (Deep Freeze).

Incidentally if you wish to access the wiki, here is the link: https://megaquarium.fandom.com/wiki/Megaquarium_Wiki
Credit goes to user FeelTheDango for the AcidicNeutral, Communal, Explorer and OpenSpace icons which I borrowed and edited for this guide.
Icons (Part 1)
This section will explain about all the icons shown on the animal information screens. Though most of these are self-explanatory, there can be some nuance to the details between different species, especially when it comes to breeding. The icons are organized in the same general order they show up in on the animal information screens, from left to right and up to down.

Prestige: Whenever a guest looks at an animal, there is a % chance that a certain amount of prestige will be generated. The number on the star shows the amount generated, while this guide will show the % chance that this will occur for 1 animal, and the # of animals needed to make that 100%. As an animal grows bigger, the % chance per individual will increase, and sometimes the base Prestige amount can increase as well.

When this icon is a superscript to another icon (e.g.), it means that the animal's base Prestige will be increased by fulfilling optional tank requirements, like having a certain number of individuals more than the needed amount, or adding more species when not strictly required.

Ecology and Science: Similar to Prestige, these show the # of Ecology or Science points generated whenever a guest looks at this animal. Unlike Prestige however, this is always 100%. Also like Prestige, these amounts change as an animal grows.

Size and Warning Type: On the animal information screen, this shows the base and max size of an animal, designated as # - #. If an animal does not grow, it only shows one number. Also, if an animal has more than two stages of development, you will have to hover the mouse cursor over the Clock icon to see the middle stages (or consult this guide). When hovering over the Warning icon, this designates all animals that do NOT otherwise belong to a special group, such as Crustaceans (so, most of the animals in the game).

Temperature: The temperature of the water this animal requires to survive. The amount of heat or cold generated by your equipment must always be ≥ the size of the tank, or for super chilled, to be at least double. Some animals require the temperature to be over the threshold by a certain % to initiate breeding.

Air Conditioning: This animal requires the tank to be Air Conditioned. The amount of Air Conditioning generated by your equipment must always be ≥ the of the tank, or for ice to form, at least double.

Filter Power: Identical to filter power provided by your equipment, these animals will increase the water quality of the tank. The amount is very small, so don't count on these to make a difference in anything larger than the smallest tank sizes.

Land and Perch: The amount of Land or Perch capacity each individual of this species requires. Each beach tank and polar dome has a fixed Land and Perch capacity, regardless of how small or large you make it. Animals requiring Land or Perch have their size stat halved when calculating the water tank capacity (ex. an animal with 40 only takes up 20 in the tank).

Water Quality: The base quality of the water in the animal's tank for it to remain healthy, determined by equipment, decorations and the bioload of all resident animals. The formula for calculating the quality has not been made public and is apparently fiendishly complicated, so this guide does not provide details on the animals' bioload unless specifically noted in-game. Note that water quality above the base threshold can improve the Survival % of an animal's offspring.

(and others) Food: The type of food this animal eats. Hovering over the icon will show the time interval between feedings, while the individual animal's information box will show the amount needed per feeding. This value increases as the animal grows. Note that the fry of an animal sometimes has a different diet.

Supplement: This animal will require a supplement every three days. It is always one supplement, and always three days, even after it grows.

Clipboard: This animal requires "observation" after the number of days shown on the icon, repeating for its entire lifespan. The observation task requires a staff member with the Feeding skill to use the clipboard tool.

Kreisel, Rounded and Abyssal: This animal must reside in a tank of this type to stay healthy. Animals without a tank requirement can live in either Kreisel or Rounded, though only Abyssal animals can live in Abyssal tanks.

Scavenger: This animal is automatically fed when any other animal in the tank is fed and does not affect the water quality of the tank. Animals with this trait will still require food every day, so do not pair them with animals that can go a day or more between feedings.

Lights: How many lights the animal will require it's tank to have. Some species require lights on their tank to initiate breeding.
Icons (Part 2)
Terrain Features: Many animals will need a certain amount of terrain features to feel healthy and at home (or dislikes the feature). From left to right are: Plant, Cave, Rock, Bogwood, Flat Surface, Floating Cover, Fluffy Foliage, Vertical Surface, Grass, Pebble and Den. Some animals will also require these for breeding purposes, as the offspring will live in these objects. Note that all Bogwood decorations will also provide acidity, some of the Floating Cover decorations have a depth requirement, and Grass, Pebble and Den decorations can only be placed on land.

Explorer: This animal will require a certain number of different decorations to stay healthy. These are simple to combine with the animal's innate terrain requirements.

Open Space: The tank this animal resides in must have a continuous unobstructed square area. There must be absolutely no decorations of any kind inside this area.

Tank Depth: The depth of this animal's tank must be at least the number shown.

Animal Type: Any animal with one of these icons does not belong to the default "Animal" group. From left to right these are: Crustaceans, Starfish, Soft Coral, Stony Coral, Anemone, Clams and Gorgonians.

No Conspecifics: Only one member of this species is recommended per tank, as any more will reduce the health of all members.

Wingman: This species must be paired with another animal with a size of the number shown or greater.

Shoaler: This species needs at least this many individuals (of its own species) per tank to be healthy.

Flying Bird: This animal can only be hurt by other animals that can attack Flying Birds.

Active Flyer: This animal will need its tank to be a minimum air volume to stay healthy.

Greedy: Consumes 33% more food and has a 33% increased bioload on the tank.

No Food Competitors: Cannot be housed with another species that eats the same food. Members of the same species are fine.

Wimp and Bully: A species with one of these traits cannot be housed with a species with the other trait.

Communal: This animal needs at least this number of additional species in the same tank.

Congeners: Can only be housed with species of the same group, or cannot be housed with species of the same group.

Active Swimmer: This animal will need its tank to be a minimum size to stay healthy.

Armored and Heavily Armored: This animal will have a higher effective size when determining whether it can be eaten. Hover over the icon to see the #. Heavily Armored animals cannot be eaten and are immune to Biters.

Acidity: All freshwater species will require a certain level of acidity to survive. This icon will indicate either neutral (green) or acidic (red). Some species can live in both.

Biter: This species will decrease the health of any animal not of the same species and at least 3 Size.

Plant Destroyer: This animal has a % chance to damage the plants in the tank. The more Plant Destroyers you have and/or the fewer plants you have will increase the % chance. With enough plants this can always be reduced to 0. Some species will count an individual as multiple Plant Destroyers.

Territorial: The combined size of the individuals of this species in the same tank must not exceed the percentage number shown of the tank's capacity (ex: a species of size 2 with 5 individuals has a combined size of 10. Therefore if the territorial percentage is 10%, the tank they inhabit must be at least 100 size).
Icons (Part 3)
Skill: When this icon is a superscript to another icon (e.g.), that task will take a longer time to complete. Staff members will need a correspondingly higher skill in that task to compensate.

Pairs Only: Members of this species must be kept in multiples of 2, or the single one will lose health.

Nibbler and Nibbleable: Similar to Wimp and Bully, A species with one of these traits cannot be housed with a species with the other trait. Multiple Nibblers will stack the health loss to the Nibbleable.

Warning: Hover over the triangle to see a list of other species that this animal may damage and/or eat. The victims are typically defined by type and a size range.

Hybrid: The offspring of this species have a chance to be a different color and/or pattern. This guide will not cover the process of hybridization, as it is purely aesthetic and not clearly defined.

Heart: Hover over this icon to see the breeding process for this species. This covers the initial requirements to initiate breeding and the offspring's diet and habitation needs.

Mucus: This offspring will require at least one parent to be present to feed.

Needs Parent: This offspring must share the tank with at least one parent. While they are growing, neither the offspring nor the parent can be sold or removed from the tank.

Predator: These offspring will lose one % chance for each animal that is size 5 or lower. Sometimes the parents will protect the offspring with an additional base % and sometimes they are Predators as well.

Days until growth: Shows how many days until this individual reaches its next growth stage as long as all of its basic care requirements are satisfied. Hover over the icon to see all of the growth stages and their timeframes.

Freshwater and Saltwater: The water type that this species will need in its tank. Some species can live in both.

Ice: At least this much Ice must be in the tank for the animal to stay healthy. Ice forms when Air Conditioning is at least double the tank's .

Enrichment: A certain amount of Enrichment decorations are required for this animal to stay healthy. Note that Enrichment decorations decrease in value beyond the first.

Survival: The base survival rate of this offspring. High water quality and parent protection can increase this, while predators and poor basic care will decrease this. This cannot reach 100%.

Eggs: The number of eggs or fry of this offspring. Every day this # will be reduced to the % (ex. 10 eggs and 70% means that the next day there will be 7 eggs).

Nice

Hey, thanks for the guide, I found it very helpful in planning my aquarium! Just one small suggestion, it would be helpful if you could specify if one or both tankmates should be fully grown first before adding them in. I got my baby Zebra Moray Eel eaten by my fully grown Volantis Lionfish. I'm guessing the guide assumes you add them all in at the same time?

Don't put too many animals sharing the same food into one tank! It makes them more prone to dying from hunger.
QNTM 4 Nov, 2023 @ 2:09am 
What's the "bioload" (in corals)? BTW some informations need update. Most notably jellyfish can't be in the same tank with non-jelly, and clownfish gives more prestige if with anemones.

Oh wow, you're right, these must have been changed when the Architect's Collection was released. I'll go over them again and should have them fixed within a few days. Thanks for pointing this out.

Thank you for this guide! I found it very helpful in making my pretend aquarium plans. That said...

I noticed there were a handful of animals for which the data in-game didn't match that in your guide. I dunno if it was changed in an update that happened after you published, or if the stats change when one or more DLC is installed, or what. Whatever the cause, here are the discrepancies i found:

angel shark: size & sale price (should be 10-60 and $742, respectively)
common lobster: size (should be 6-22)
cuckoo wrasse: size (should be 5-10)
giant pacific octopus: size, price, animal/crustacean warning (30-100, $2244, 1-40)
longhorn cowfish: starfish warning (should be size 1-3)
pie-crust crab: starfish warning (should be size 1-3)
turbot: starfish warning (should be size 1-7)

I'm happy to provide screenshots if you need them. In case it turns out to matter: i have no DLC ATM, but don't know how long that will last :)

288 hours into this game and I just found out about the not eating crustaceans thing.... this opens some interesting options.

Thank you for your guide

@Alejandro Monteagudo
Correct, Blacktip Reef Sharks pose absolutely no threat to any Crustacean.

Starfish in this game are NOT coral eaters. They are in real life, but for some reason the developers decided not to include that.
BlueFénix 30 Jan, 2022 @ 2:28am 
Does this mean that the blacktip reef shark will not attack crustaceans no matter how small?

Also I thought starfish eaters were like coral eaters, and eat them no matter what

I was certain they did

ok, thank you for the help
