Well I gave my oscar and catfish's some silver sides tonight and my oscar had four of them in his mouth at once trying to eat them, well I picked up a 36" grabber thing from the hardware store today and god does that come in handy when you have a 33" tall tank :/ lol. anyways I took the grabber and pulled/ got him to spit them out and I gave him one and pulled the others out since now my cats wont touch them? and hes been laying in the corner of the tank since he was eating the last one. could something of happened when he was trying to swallow four silvers being the pig he is?
