We just got a new ADF
a couple days ago. He has a fuzzy white substance on one of his legs. It seems to be spreading up his leg. He is periodically lethargic, floating at the top of the water and unresponsive. At other times, he is active and eats.
We did try to put him in the same tank with our other ADF
, but the older one was aggressive toward the new one, so we switched the new one to a different tank.
Is this a fungal infection? We have had our other ADF
for 3 years with zero problems, so this is new to us. Thanks!
