After my sharks died I went and talked to a fish specialist at a fish place here in VA Beach... I brought in a water sample... he checked pH, GH, KH, Nitrite, Nitrate, 2 Ammonia tests & Phosphates. I also showed him 4 or 5 pics of the 2 sharks that died.
Basically my Catfish and Cichlid in this tank as well aren't affected by whats happening to my Balas. My smaller 7" Bala definitely showed signs that it was internal.
In the past 24-36 hours a 1/3 water change w/ RO water was done & I was told to medicate with Maracyn b/c the Balas are obviously showing signs of an infection with cloudy eye, the shedding syndrome & frayed fins. One Bala looked as if his mouth was stuck just hours before he died and my last one that died had a red line under his gills & around his one side. My catfish and cichlid are still eating when I put about 10 pellets of food in. In fact the cichlid practally ate them all up. My water quality was ok... basically the Prime & Stability dosages I was doing was helping lock up the bad ammonia. With the water change & the Maracyn so far, everything seems to be ok, but just taking it hour by hour...
Like I've said before... it's really difficult to figure what to do, when literally every person is telling me something different. This guy at the fish store I'm working with has been leading me in a positive direction so far so it's really been only one of my best options as doing something about it here since I seem to have made a lot of bad moves up till now...
