I have a pair of angelfish that have been laying eggs for the past 5 months without any problems.Two days ago I noticed the female has a swelling where her breeding tube is and she hasn’t lay eggs as usual. She eats and poops. Please give any advice as what could it be or possible treatment.
From this angle it kind of looks like a prolapse to me. Not sure if there is treatment for that besides keeping the water clean if thats the case.
