I've noticed this strange red lump on my fish's ventral fin. At first I thought he just had a weird fin, but it is only on one side and looks very much like a growth of some sort.
I'm wondering what it is or if anyone has ran into this sort of thing before.
He is very active, feisty, has a good appetite, doesn't seem to have an issue with clamped fins, struts about the tank etc. Pretty much thinks he's the boss, has a great personality.
He does glass surf quite often though.

Symptoms and Treatment
How has your betta fish's appearance changed? He actually looks way better then when I got him three weeks ago. Colourful. So, improvement I suppose.
How has your betta fish's behavior changed? Not much, he's still active, healthy appetite. Sometimes I will catch him laying on the leaves on his side, but I think that is just what he does, not a symptom.
When did you start noticing the symptoms? 2 weeks ago.
Have you started treating your fish? If so, how? Aquarium salt and 100% water changes once a week.
Does your fish have any history of being ill? I don't believe so, the petshop didn't know much about him.
How old is your fish (approximately)? Not sure, I just purchased him a short time ago.
Here are some images, they are decent quality, but it still seems rather hard to tell. :/ He is his temporary tank while I change his main tank. He also fears the red monolith that is my camera and would dart away frequently, so shots were hard to get.
