i've always wanted to keep an oscar with a crayfish or two. how do you guys pull it off without the oscar eating the crayfish? or the crayfish eating the oscar if the oscar is still young? if the crayfish have caves, do the oscars make an effort to dig in there to get them?


I think it's just luck when it happens, we used to give our oscars a crawdad for thanksgiving but this year, they adopted it! When we moved them all to the 125g we added our big clown knife to the tank and the knife and the crawdad became buddies and shared the hiding place we put in for the knife. Now the crawdad shares a tank with a jag, when we put feeders in, the jag eats the heads and the crawdad eats the tails. It's weird but it works.

That will be pretty awsome. What is the purpose of the crawfish in sumps? Oh yea and I think a good name would be Leroy. HAHAHA

The purpose of crayfish in a sump is to help keep it clean These guys are scavengers, so it's a perfect environment :o)

Also, I think I'm gonna go with Rollins. I'm out of town right now, so hopefully he'll be alive. I didn't see him in my 20 before I left the house, so I'm hoping he just burrowed. The fish in the 20 aren't really big enough to eat him right now. Well, then again. But he's a beast. I think he'll hold his own
 
i threw in a bunch of small crayfish for the fish in my 220 and about a month ago i was doing a tear down and rebuild and sure enough one made it. he was about 2" now with one arm growing back(think they took that one) i guess he must have just been living under a rock or something. i'm also suprised my blue crayfish thats about 5.5" didn't eat him. hes eatin all my fresh water clams and my snails... bastard. never thought about keeping him in the sump. dont you think hed get sucked in to the pump inlet?
