Can anyone help me identify what's causing this?
He is one of ten white clouds I've had for about 4 years, and has suddenly become tiny, deformed and inactive, however he is still eating. Checked and re-checked my water quality, no ammonia, no nitrite, correct ph... I have had a nitrate spike/algal bloom recently, which has cleared up brilliantly. Have tried fungal treatment already but with no success. All other minnows are in as good a shape as ever, as are my pair of dwarf gouramis and weather loaches.
Any ideas? My only thought at the moment is plain old age...? Only guessing on lifespan though
Cheers
