Pale Cory clamped fins (Velvet?)
I have a cory. He is the last of his group. He has been doing fine for a while. He is about 6 yrs old or older.
Last week he was swimming around going to the top a lot hanging in the middle.
Then a couple days ago I saw some damage on his dorsal fin. That healed up but now he is lying at the bottom of the tank listless and pale.
Tank has been cycled and up for 2 yrs.
no new fish added recently
It is planted there is a green algae bloom.
0 Ammonia, 0 Nitrites and Nitrates are below 5.
Ph is 8.2
Any ideas?
Temp hasn't shifted much usually around 78. Trying to find my thermometer to verify.
*Update. might be velvet. I had a suspected case in another tank. But usually let equipment dry for a day or two before using between them.
