So I noticed my payara had stopped eating feeders and was just killing them 2 days ago and I was getting worried until today when i saw him swim over all excited when I was feeding my rays! he's obviously been stealing prawn for them the last 2 days and just waiting until i was gone. Finally no more feeders!
I never thought this day would come because I didn't want to use the starvation technique just in case he started nipping at my other fish or taking chunks out of them. I did manage to take a video of him eating 1 piece I will try to get some better videos next feeding later tonight.
