I have a 125 gallon that has two hybrid blue gill, two yellow perch, three long ear sunfish, and a yellow bullhead. A week or so ago one of the perch started swimming nose down at the gravel. From what I have been able to find online it is likely swim bladder and it will either recover or it won't. Everyone else in the tank is fine. The perch is eating and not really showing any other signs of distress. I have noticed his tail is starting to get a bend, which I assume is from a week or so of swimming nose down.
Any thoughts, advise, input??
Thanks
