So my brother and I have somewhat recently picked up a fluval flex 10gal freshwater tank. PH and Nitrite levels are all perfect. All fish and crustaceans are doing swell (danios, neon tetra, mexican dwarf lobsters, ghost shrimp, cory catfish, and german blue rams). 1 of our 2 rams has recently sprouted something on the left side of his head. It started small, so we bought and added lifeguard all in one protection tablets and started putting them in the tank accordingly. After using all of the tablets, he does not seem to be getting any better, in fact the wound/parasite has grown larger. His behavior is not off in any way which is strange, he is eating fine and swimming and interacting normally. We have been feeding them a mixture of flakes, blood worms, shrimp pellets and bug bits. I'm attaching the best photo I could get of him so you guys can get an idea of what I'm talking about. Please help if any knowledge!!!!!!!!!!!
