I have a gold flowerhorn about 2 1/2-3 inchs long .2days ago i notice a black spot on its head ,it seems to be getting bigger.It seems to be spreading on his head ,now i see little spots on his side.Is this common in flowerhorns?
Something similar is going on with my delhezi... He is dark normally but its a grey patch of scales...It turned whitish. Thinking bacterial or fungal infection?
How long have you had it ?
