I just noticed this night that one of my beloved
neon tetra is sick! I found it hiding behind the piece of
driftwood in my tank away from the other neons. It was opening and closing its mouth very rapidly. It has a bloated belly. It does not look fat, but rather its whole belly area is enlarged. Also, it looks as if there is a lesion right above or on its anus. Its colors are also duller than the other neons, even when the light is off.
I did not see any scales sticking out so I do not think it has dropsy. I hope it doesn't have neon tetra disease since I love my neons very much. It does not appear to have any curvature of the spine or irregular lumps, fortunately.
Unfortunately I do not have a quarantine tank. Since I live a small dorm room I don't have enough space to set one up. What do you think my neon has, and what should I do?
I have attached a few pictures. I appologize for the poor image quality. My camera lens needs to be cleaned. Thank you for taking your time to help me deal with my first ill fish.
