Recently bought a beautiful amazon blue angelfish and a leopard angelfish from my LFS. They looked fine and active in the store, but we've had them for around 3 days and they're starting to show a couple of little white spot type things on their lips. My boyfriend and I disagree on whether or not these white spots are actually sticking out or not, but the one on the blue amazon looks a bit fuzzy to me. The one on the leopard doesn't really look fuzzy at all and instead looks a bit...pimply?The angelfish are very active, eating and following our hands around when we are near the tank. They also are not isolating themselves at all and actually sticking together in a group on one side of the tank. My water parameters are: Ammonia: 0.25 ppm Nitrite: 0 ppm Nitrate: 20 ppm (our tap water comes out at this) pH: 7.4 Temp: 80 F/27 C I'm thinking the tank could be in some sort of mini cycle? Which is weird because we bought this tank from someone and it was matured over a year. We are using this as our 'quarantine' tank at the moment as the little jurupari that we have in there at the moment are new as well. We'll probably be using this 55g as a grow out and move the jurupari to a larger tank once they get bigger (they are only about 2 inches long at the moment). None of the other fish in this tank are exhibiting any signs of illness. I'm extremely worried about these fish and don't know what I should do since I don't know what this is. Any help or advice would be appreciated.
