Hello list. A curious red growth has recently appeared the right eye of my Bumblebee Oscar . He is about 8 years old and never had any health issues before. I typically change 85% of the water from his 5’ 120 gallon tank once a week. The growth appeared about 10 days ago and took about a week to get to its current size. I increased the water changes to 80% every 2-3 days but think he likely needs some kind of medication.
I test the water regularly and his nitrates are around 10 or less, ammonia and nitrites are 0. I clean out his FX4 every couple of months and the sponge filters once a week.
He shares the tank with a handful of small clown loaches.
Any advice on what this is and what I can do to reverse it is welcome. Thanks in advance.
