One of my females has had her tube down for a cpl days now. She had moved her pot n gravel so I thought it was usual, until this morning. I believe she has bulging anus, her tube is still down, but now it looks like a pea sized chunk of meat is also hanging out. Water changes are done weekly, at a min. Did a 30-40% change this morning before I had to leave. Her colors have come back a little, but what is the best way to cure this? Meds or just WC and salt?
