I had 4 cory mellini in a community tank, now I have 3. One died a little while ago. I've been away but home for 2 days and didn't see anything wrong. Symptoms - red swollen belly, enlarged,reddened vent, also very small red marks at base dorsal fin.
They've never quite schooled, three always swam together, the other just hung around by itself - this is one of the three.
Any guesses - is it contagious? I don\t want to lose the other 3, let alone anything else. I've had them approx 8 months, nothing has gone in since the angels 3 weeks ago
