Injured fantail question
I just moved my fantails in to a new tank that is not completely set up yet. This morning, I found my smallest fantail sucked up to a temporary small pump I have in the tank.
I shook him loose, he swam to the bottom and just lay there a while. He has hemorrhage marks on his side and a small dark red protrusion from his anus. I placed some food in the tank, which he eagerly swam to eat. He then swam back to the bottom.
Is he doomed? I have no idea how long he was like that. It could have been hours overnight.
