Stupidly curious question

[BLUElobster99]

I have a 10 gal with a 4 inch electric blue crayfish
Ummm I really want some dwarf puffers and they are on $3 at my lfs so is it even worth trying to see if my cray will coexist with them?

I had him in a 29 and he never bothered any if my fish up until a territorial issue arose with him and my Pleco

I wouldnt try it in such a small tank the chances arent good when not given a lot of room

Hello,
A 10 gallon is just too small for an blue/electric blue crayfish. So adding more fish won't help, and he will most likely kill them. I suggest upgrading to a 20 gallon or more, or putting him in the 29. Make sure the fish don't stay at the bottom too much.
