Until last week I had 4 silver sharks in my tank - then last Wednesday one popped its cloggs which I wasn't too worried about it happens from time to time. Then over the weekend I noticed that one of the other's dorsal fin and little fins on its tummy (sorry not sure what they are called) had gone red and it didn't look very well - just floating around a bit and not rushing around as normal. I inspected the tank this morning to find it belly up. I've tested the water and all seems ok. Have they got something that I need to be medicating? All the other fish seem fine.
Any help greatfully received
