I picked up this ram from my lfs about 2 weeks ago and we was a bit skinny then too. He was in a tank with a bunch of barbs and his fins where a bit torn but they have healed. He still goes to eat but he has been staying at the bottom a lot. I have not tested the water parameters but I do a 25% water change each week. I have been feeding him Omega One tropical flakes and pellets, newlife spectrum cichlid pellets, and I feed frozen bloodworms a few weeks ago. I am worried about this fish, I have plenty of apI medicines on hand If I need to use them. The stock in the tank is 5 zebra danios, 1 dwarf flag cichlid, 1 american flag fish, one of those little maccus plecos and the bolivian ram.
