THESE BLUE EYES! keep getting sick >.<

[Australian natives]

another one is suffering disease. one has pop eye and a large white spot on its fin, i am thinking it looks more like fin rot than ich though. there is also a white spot on below/on its dorsal fin, which i think ma be some columnaris. hopefully it will recover like the other 3 which has have had diseases in the past week or so.

i am at a loss as to what is causing the sicknesses. i have been doing daily changes of water for a long time, and all the other fish are fine. unless maybe the first fish has just been passing its sickness on to the others, and recovering. if that is the case i hope i can end it with this one.

i am goign to try and catch it at some point today, but i don't like my chances.

P.S. the pop eye is pretty nasty looking, there is a fluffy white ring around the rim of the eyeball. =S.
