I got a free 1.5" Ocel at LFS on Friday because he was very beat up by tankmates. He was eating live blood worms and today was his first minnow session. So, he eats three very small minnows and I leave to feed my large cichla. When I came back he was floating sideways at the surface and sometimes splashing with his fins. I immediately grabbed him to check his mouth, nothing in there, then I held him in front of the filter so to get water passing through his gills and as he started to wriggle I let him go. It took him about 5 minutes of swimming and then sinking and floating sideways but, slowly he went back to normal. Water params are good and he seems to be fine now. Does anyone have any clue as to what might have been wrong with him? Scared the crap out of me for sure.
Here's some pics.
