Not too sure if it is fin rot or not can anyone help?
So Ive recently moved both of my betta fish from there tiny bowls into a 5 gallon tank with a splitter. They each have 2.5 gallons a piece, and have enough room to swim around. I do have a heater and pump to keep the water conditions perfect.
One betta is a crowntail and is very agressive, and the other is a overly active halfmoon.
The halfmoon is who I am worried about. He use to be a very elegant white now he's developing a yellow colour. He doesnt flare at the crown tail or his reflection in the mirror. His lower fins are also damaged, and I dunno if it is fin rot or if hes just worn it down.
how can i fix his fins I want him to grow big and healthy. Does any one have an answer?
here are a few pics of him, I dunno if you can see it in the pics.
