I like going into the crab with a bomb (same with the Mushroom boss). Blowing up his minions turn 1 or turn 2helps a great deal, since you can focus on the boss immediately. The minions have really high physical defense but 0 magic defense, so bombs can clear them turn 1 on lower difficulties.

The crab hits really hard, but he only hits one target. So you want a really good tank up front and try to focus on blue symbols for freeze and the shield symbol for survival, and maybe the symbol that gives you heal if you can. But most importantly... GET A MAGIC UNIT. 70 physical defense but 0 magic defense. The only way you're going to kill him reasonably is with magic damage. A 4 unit party, one tank and one magic dealer, should be enough with shields/heals. A 2nd magic dealer is better.
