i have 5 iridescent sharks, 4 dark and 1 albino.
yesterday, the albino died. Before it did, I had the following observations:
- small bubbles flow out of its gills once in a while even if it does not go to the surface
- did not swim like stupid (iridescents keep swimming like crazy)
and now, another shark is showing the same symptoms. i googled it up but i only found gas bubble disease. which could not be since the symptoms (which includes bubbles on skin) did not appear.
anybody know what's killing my sharks 1 by 1?
by the way, 2 bala sharks and 2 plecos are looking fine.
