Ok yesterday and today i have seen my senegalus regurgitate his food. I thought it was because on friday i switched to massaviore delights but today i gave him his regular food and he did the same thing. None of my other bichirs are doing this. He is also getting agressive he has been picking at my electric yellow cichlid which use to pick on him(how things change). all my reading are good and none of my other fish seem to be having a problem. I clean my tank every week 30% water change and all. He is about 6 1/2 inchs and he is getting big fast and i dunno what to do.
