Hi, I am not sure what the lumps are it is possible they could be tumours which you cant do a awful lot for, he does seem to have a little infection going on, on his body. You maybe able to cure that with turning the temp up a bit, and just keeping his water really clean. I would recommend that your maintenance needs to be upped you have 2 fish in a 5 gallon tank. so I would recommend two weekly water changes of 50% and once a month do a 80, 90% one, keep those nitrates down and water quality up. I actually do a 50% one once a week and 80% once a month I have one betta in about six gallons.

Hopefully someone else might be able to help with the lumps a bit more.

Thank you so much for the input Beautiful Betta!

I've bumped up Steves water temperature to 27 degrees celsius and will be planning a schedule for the water changes :)

And I hope so as well. I read elsewhere (in a heap of articles and forum posts), that the lumps could be tumors and as long as Steves behaviour doesn't change he'll be okay. So that'll be the positive thinking on my behalf! (Until I'm told otherwise)

Looks like what I'm dealing with one of my boys. I read here from several post that it could be lymphocystis. I had a white scale that has raised into multiple white scales to a white lump on the side of my boy.

Lymphocystis is either white or pale pink in colour, so I do not think it is that. This looks like a lump forming from underneath rather than coming out of the scales.

It looks white to me and that's how my boys look until it got bigger and bigger.

It appears to be pushing up from under the scales which is a sign of two things- A cyst or lymphocystosis.
A cyst will appear to be full of something, likely a fluid or puss-like substance and will burst in time.
Lympho however has no clear way of treating it and instead is mostly solved through hazard reduction- as long as the fish remains perfectly unaware of his lump then you can safely ignore it. if however it continues to grow and begins to affect your fish's swimming or bouyancy you need to make his tank as disabled friendly as possible so he doesnt get exhausted fighting against his own weight.
