Crayfish help?

Does it look anything like my fella?

alright, I'll try to get some pics tonight. That's a wicked nice looking cray dude....
 
Well, I got to take another actual look at the tank today (Called to see what the plants and cray looked like), and some plants were really nom nom'd on. He looks A LOT like Jawa's blue dwarves, except bluer. Can't get a pic, maybe this weekend I can get one.

Do you think that he would be ok in my 37 with my goldfish? It's not planted, hence putting him in there. The goldfish is a small black moor.
 
If I'm reading / understanding what others have posted right, nomming plants means he's the type likely to also nom fish. There's a good chance they'd be fine for a long while, but one night when the cray is hungry and the moor is asleep...
 
a long while is all I'm looking for. I just want a temp home for the cray, until I decide what to do with him...
 
he's being returned as we speak, my betta looks beat-up so that's the last straw. I had no problems for a week, and then it looks like he went crazy overnight.
 
thats why he was returned, looks just like the blue dwarves. Whatever, the betta will be fine and the cray was only 5 bucks. Good learning experience I guess....
 
Personally I think baby crays look just like dwarf crays. But then I'm horrible at IDing things that don't have huge obvious difference. :laugh:

The wild ones I catch occasionally look just like dwarf crays when under 1". At least until they hit a growth spurt, double in size overnight, and suddenly look like mini normal crays. They do live peacefully with Guppy fry and get beaten on by Orange Dwarf Crays half their size until that point though (which is really weird to watch knowing what the adults are like).
