Hi, this is my first fish and I am having a hard time identifying what's going on with its tail.
When I first got him I kept him in a fish bowl and pretty much did everything wrong.
He was looking a bit rough a couple weeks ago so I did some research and got him a bigger (3.5 gallon) filtered tank and a heater, treated the water with Prime+ and doing 25% water changes daily. He has his color back, eating and is very active.
But he has this moldy clump on his tail and it shines gold in the light. He's not scratching against anything or acting weird and hoping for some advice or thoughts if it should be treated.
The problem area is the bottom of the back fin
