Friends For Cray..?

I have a cute small crayfish in a 10 gallon. He is currently 2.5 inches big.

I originally had the 10 gallon empty for a small community tank I wanted with:
ghost shrimps
mystery snails
and maybe one guppy or other small fish.

Then I got my blue crayfish which was unexpected (boyfriend saw him and had to get him) so is there any live being that can be his tank mate at all?

 

Warning! A cray will destroy all of those in hours. They are not passive scavengers but active predators.

I keep Marbled Crayfish (the most docile of cray aquarium crayfish as far as I can find) and even they will not suffer any snail to go uneaten, and still take guppies once in awhile too. I lost 2 of my best females in the past 48 hours while they slept. Plus they destroyed all my plants.

Sadly, the only things that can live with them are things that will eat them. Even other crays are a bad idea, because they fight.

If you want a community tank, re home the cray. They are interesting, but vicious. It's like keeping a little tiger.

 

Scratch that. I had an Orconectes Virilis (the virile crayfish) which was rather aggressive and she liked to escape a lot. I had fathead minnows (common rosy minnows sold as feeders) in there with it as a food stock. Instead they pushed it around and ran the tank until they died (long after the crayfish). They get about 4 inches long and look like tiny salmon/trout when they reach adulthood.

Basically don't add anything you want to keep, but sometimes things you think of as plain food turn out to be rather beautiful if/when they get the chance.

 

Okay! I was actually thinking of those (the rosy minnows!).
I love the blue crayfish's personality and antics so I think I'm too attached to re home him

I wanted to keep his tank interesting so maybe I'll get cheap plants? Who knows, I had anubias with him and even though he didn't eat them all he gave them quite the makeover! He seems to want his plants to float and be somewhat leafless. Maybe hornworts would be okay

But I might get one or two minnows then and see how it goes?

 

Small fast fish are generally ok because the cray isn't fast enough to catch healthy fish. There is always some risk of losing fish though. If they stray too close to the cray and give it a chance, the cray will kill them. I wouldn't waste my money on plants, but add them if you want.
