I have been having 30-40 small 1-3 inch BG die each day for the past 8 days. No LMB ,HSB,or TFS have died in my 9 ac pond.Aeration running after start-up.
It has been advised that I try a terramycin treatment to add to fish food but I can not locate any terramycin unless given a prescription by a veterinarian. Any idea on finding a veterinarian that has fish knowledge or how to acquire treated feed ?
