Crayfish tankmates

[Ernane Tulio]

hey guys,
For you thats experienced to crayfishes.
Im thinking about get an crayfish and I wonder if it will be fine with 2 young polys or will be meal (ornatus 6" / endli 4") and a fire eel (about 8").
There are some cyclids too, but they are small (2 red parrot fish 2" / 2 geophagus 6").
Its a 75 galoon tank, lots of hiding spots, some floating plants and anubias, moderate light.

I have another smaller tank (20g) with a red dragon FH only (about 5") and I am wondering the same
Is it gonna work?

TKS!

Crayfish should not be kept with fish because the crayfish will eat any fish it can get a hold of. The only fish that a crayfish will not eat are ones that will eat the crayfish.

My 2"-4" Andinoacara cichlids will attack en-masse and
make mincemeat of any crustacean even slightly larger than they are.


A few of the larger ones survived up to a couple weeks in my 180 gal because there were plenty of places to hide, but even they eventually succumbed.

Thank you very much.
In fact, I put them togheter once, few months ago, when my FH was in the same tank. The crayfish didnt last 2 days. I came home after work and there was the carcass and the p. endli and fire eel eating. However, I couldnt figure out who killed him. I though it may be the FH or the polys. FH because his agressive behavior. Polys because theyre predatory. But none of the other tankmates seemed mind the crayfish, they didnt touch it.
