I’ve had a pair of EBAs for about two weeks now and I just noticed this bump on the eye of one of them. They are in a 40 gallon aquarium with a bristlenose pleco as a tank mate. Temp is 78, pH is 7.6, very hard water (magenta on aquarium co op test strip), and I’m doing 25% water changes weekly. I did one round of paracleanse as a preventative treatment when they arrived but that is all they have received for medications. She seems to be acting/eating normally and swimming laps with her partner. Is this something I should be concerned about? And should I do anything to treat her? Thanks!
