I've been hooked on watching Green Aqua's videos a couple of years ago and decided I would have a go at making my own Iwagumi in this simulator. And theres a few things that I would like to see added to the game.

The Fish variety is great, but I would like to see more variety of other animals, like snails, worms, and crayfish, and other small insects

This needs more lighting options for spotlights and angled lighting.

BIG aquariums, BIG square aquariums that I can place as the centre piece for a room.

Increase the size/scale of rocks and objects further, like be able to fill the entire aquarium with one or two rocks. and make other manmade objects like pots be able to be made miniature to make piles of treasure

the terrain tool needs to be more usable than just one click, how about holding the mouse as you drag around the aquarium to make interesting terrain designs.

More options for plant life and weeds.

The object brush tool for scattered small rocks and small plants only has a few options to choose from and the placed objects have too much space between them.

More management gameplay needed. yes you CAN feed your fish, but you dont need to. you dont need to adjust temperature levels, or maintain your aquarium in any way.

I would like to see the fish animate more. Behind Glass is by far the best animated fish tank simulator I've seen so far but I would still like to see more animations, like fish cleaning algie off the rocks, fish randomly pecking at objects and seaweed and fish schooling

More options for types of substraight and sand and pebbles and rock.

Day and Night cycle for natural lighting.
