red tail catfish feeding problem

[agra113]

Hey guys i have a 15inch RTC on a 10*10*1.5 ft concrete tank. I want to put him ina a 6*3*3 ft glass tank. But after i put him in the tank he wont eat for days. Even when he start to eat he spits them out and he swims like crazy back and fourth. So when he wont eat i put him back to the main tank. How can i deal with this problem ??

Probably stressed from moving to such a small space, maybe better to leave him be in the concrete tank, perhaps get a juvie for the 6' and let him grow out in that

Welcome to MFK's. Where is the location of your avatar? I've seen it in other pics and everyone is holding a giant fish.

Please, provide your water parameters and please consider earnestly, if you will, following this protocol when asking health / appetite related questions: http://www.monsterfishkeepers.com/forums/threads/fish-health-diagnostics-read-before-posting.210102/

IIRC, you have had problems or even lost two 2' Wallago leerii and were asking for help but could not provide basic water test results on ammonia and nitrite, so we could not really help you, no?

Im sorry to say this but i found him and some of my other giants dead in my tank. Some pacus all over 1.5 ft and one fish native to my country around 1.6 ft

Sorry to hear. We can only guess. Most likely the water was poisoned with ammonia and/or nitrite or it was not aerated enough.
