I had this black angelfish for a year now. She had already spawned five times and this week she was becoming fatter and I thought that she was ready to spawn again. Her papilla grew as well. Yesterday evening she was ok but a bit more bloated than usual. I fed her bloodworms thinking again that she would spawn during the night. Instead I found her dead in the morning. I saw some eggs protruding. Could it have been an internal parasite or the cause of being egg-bound?
