Black Neon Tetra with missing vent?

Recommended Posts

Hey there,

About 3 days ago I noticed my black neon had a prolapse and had a protrusion under her vent. I used some Methylene blue and Epsom salt to help, after 2 days she expelled a few eggs and a day after she has a triangle-shaped hole under her vent. She doesn't appear to be stressed but not sure if I should euthanize her. I have also used Stress Guard from Seachem as an antiseptic.

All the fish are usually friendly, the rasboras, black neon and neon tetras are always schooling together, the Dalmatian mollies are very friendly and show no signs of aggression towards other fish. The snails, corys and loach mind their own business at the bottom and are very peaceful.

Thank you for such detailed information about the fish and its tankmates and environs.

If the fish doesn't appear stressed, and is otherwise eating and acting normally, then I would leave it as it is and it may heal by itself.
