So i bought my Brachyplatystoma platynemum about three weeks ago and I'm getting a little worried now.. I was told he was on feeders after I already got him home, but I shook it off because i've broke lots of fish off of live. I've tried (With lights on and lights off) Silversides, tilapia, earthworms, krill, beefheart, massivore, carnisticks, just about everything i have. Everytime I put food in by him he darts off like he is scared of it and will not touch it. Tank info is 75g with sunsun 304b, 80*, PH is about 7.8, Ammonia and Nitrite 0, Nitrates are 5 ppm. Im setting up a wetdry on it today along with the sunsun. I have a powerhead in the tank because i read that they do like current. Hes about 8-10" and his tankmates are a 6" Mala Wolffish and a 6" Achara cat. He watches the other two eat anything that comes in the tank so he has teachers. No aggression what so ever in the tank, his scratches are from darting into the filter intake and heater. Im about to throw in the towel and give him feeders. Ive had about 5 in qt for over a week so theyre ready to go. I've never had this much trouble getting a fish off of live. I don't know what else to do because he is getting skinny and I dont want to lose him.. Thanks for any advice.
