I've seen fish with pop eye, this one is different. Its head is swelled, the eyes are bulged, and it lookes like something is eating away at its head at the same time.
The strange thing is that the fish is acting normal.........it gobbled pellets last night and is still eating. It's not being picked on from what I've seen, but seems to get worse by the hour.
Can a parasite do this? It has stringy white crap that I noticed tonight too.
