Hey guys, I went to Uncle Ne'ds today and came home with another impulse buy. I picked up a little blue crayfish (1" roughly) and was planning on keeping him in my non-planted 37.

What else could I keep with him? I really want to put my 2 Jurupari babies in there (both are about harly rasbora size) along with my syno and a school of Red Eyes. The Jurupari's and synos are just in there for grow-out, and will go into a 125 once they reach 3-4".

So, will this work with the cray? What do you guy's feed yours? Are there any "cray safe" plants out there?

Please help Clawsius Cray and his awesome new tank.

Thanks
Cam
 
Do you know the species of crayfish? The crayfish that I most frequently see sold as 'blue crayfish' are P. alleni and C. quadricarinatus. Both are not dwarf species, and can be aggressive hunters. They can grow to six to nine inches.

I know that doesn't help you, but without knowing the species of crayfish you have, it's not possible to say what can be safely housed with yours.
 
neither (I think). He looked VERY similar to the Orange Mexican dwarf cray at the store, and had very faint blue coloration.

CPOs would not eat fish- not catch them anyway- dead ones they would.

You can get Cambarellus Shufeltii to have a blueish tint to them by feeding them nothing but vegetative matter (so I've read- never tried)... protein turns them sandy to brown.

I've never seen them "BLUE" though. Not like the Alleni.


If you've got a live plant you don't mind sacrificing a bit of- try putting it in the tank. If he eats it he probably is not one of the Cambarellus dwarf species. Being blue though I'd be surprised if he were a dwarf.
 
Honestly, we can't give you a definitive answer, without a good picture of your cray. If you have a young non dwarf crayfish, it most likely will be well behaved, until it matures.

If you can't post a good picture, I would then recommend that you be cautious. Never put anything that you aren't willing to loose to predation in with it.
