Balls. I think one of my juvenile angelfish has velvet. It's slime coat appears thickened -particularly around the dorsal area... although this may just be where the light is catching it... It's fins are half clamped and it's hanging around just below the surface... it's also beating it's pectoral fins awkwardly almost like they're 'sticky' tested the water... everything is unchanged and no cause for alarm there. None of my other fish appear to be troubled at all, and the fish is still eating.... but then goes and sulks afterwards. My tank also has a pair of jewel cichlids, some corys, a couple of clown loaches and some otocinclus. I've got a few live plants that i bought cheap from pets at home because 'the pots are broken and you won't be able to keep them without the pots' but that's pretty much all because i was going to rescape this week. Oh... the tank is 240litres, has a eheim 2028 external and 2012 interl with extra module... and a vecton 2 600 uv steriliser. what is the best treatment for velvet? ...also, i'd prefer something that isn't going to kill my plants... filter bacteria, or stain everything it touches... any suggestions?
