I was setting a tank up for these crayfish. I stopped halfway and was about to get a few crayfish, but I stopped because it would require more care (feeding and tank maintenance time). Plus my wife won't let me have more than 6 fish tank, so I have to be very wise to what I put in my tanks from now on.
Some people are against putting in crayfish too many times inside puffer tanks because they have a chance of injuring their puffs. But others say they are exposed to these dangers out in the wild.
What does your craytank look like?
