The crayfish in my tank are responsible for most of the little caves that my fish call home. The best part is all they ask for is to be well cared for.
crayfish often think they are bulldozers. i've had mine move incredibly heavy things rather than just walk over them.
Yea i cant believe my piranha, they eat them in one chomp!

are you saying you feed your pirahna crayfish or that your crayfish eat pirahna? because either way could be true. while crayfish can be a nice snack for many large animals i would think it would be expensive as daily feed. adversely, i have a large destructor who could eat most pirahna but feeding them pirahna is expensive and not good for them as most types of crayfish don't do well on a strictly meat diet. they need mostly plant matter. i feed mine mostly peas, organic spinach, algae wafers, hikari crab cuisine, and fresh tilapia as a bi-weekly treat.
