Hi. I have an adult OB/Red Zebra, about 3.5" long, in my 55g all mbuna tank. The pH is 8.1, and Nitrates are under 15ppm.
Very quickly, over the last few days, it has developed the following symptoms:
1. Disintegration of fins, especially dorsal and tail.
2. Whitish/iridescent sheen on surface of body.
3. Apparent loss of movement of pectoral fin on one side of body (it's not using it and it is listing)
4. Sunken stomach, as if it hasn't been eating (not previously detected)
There are no other fish showing any signs of problems.
Wondering, what it is? How should I treat it? Should I treat the entire tank as a precaution?)
The only recent change to the tank is that about 2 weeks ago I added 4 small snails from an LFS cichlid tank (on their recommendation) to help cope with algae. I have had no other illness in this tank, except for a case of bloat about a year ago. The tank has been established for just over a year, and I have had this fish for the entire year - it was an adult when I got it, so I have no idea of its age - conceivably, it could be old - it's the largest fish in the tank.
Thanks!
