what can you keep with a blue lobster?

You could get more crayfish. I heard they can breed easily.

My blue crayfish ate my CT betta and my tetras =( Don't put in fish small than the crayfish, but also not too much bigger. They'll be each other's meal.
 
Only if you have a big enough tank, they need at least 20g each for the blue ones... or so I've heard.
