Looking at adding a 3 inch shovel nose cat to my 75 until its big enough for the big not tank. I have 2 3 inch crayfish in the rank as if now. They don't bother the far if the bass. Will the cat work with em ?
you'll need a divider for the catfish or a separate tank,
a crayfish will find ways to hurt, kill, and eat anything that wont eat it,
what kind of crayfish are you talking about?
and what kind of bass and how big is it?
