Hi....I'll try to keep this brief - My original post was here http://www.bettafish.com/showthread.php?t=107702
Basically, my betta had this lump appear on his side that steadily got bigger and bigger. In my original post, it was said it may be a tumor (which I don't think it is now...), and OldFishLady suggested I use Epsom Salts for 14 days and IAL, which I did, but to no real effect.
Then, the poor guy started getting a bit of fin rot (this was after I listened to the petco guy who told me his lump was probably because I changed the water too much...I took his advice and started changing the water in my 2.5 gal tank 50% twice a week and using a gravel vac.)....I was using the IAL at the time too.
Well that was a bad idea. After about 3 weeks of this his whole top fin started showing signs of fin rot. He went off his food for a few days too.
I immediately did a 100% water change, got some aquarium salt and some stress coat, and did 10 days of 100% water changes every day with 1 tsp AQ salt per gallon, plus stress coat. That was about 2 weeks ago. I now use stress coat every time I change the water, which is 100% twice a week.
After the AQ salt treatment - his lump started to change. First it changed to white, but was still a lump. Towards the end of the 10 days, it seemed to burst open, and now is a white hole, and looks like a gaping wound....pretty nasty. I actually do think it is trying to heal. It must have been some sort of cyst.
I really want to try and heal this up now....
I switched to a better food, Spectrum Betta Formula, and am also feeding frozen brine shrimp. I still put stress in all his water changes (I use Reverse osmosis water with liquid R/O Right minerals to replace minerals in the RO water). The temp is constant at 80 degrees (we are in FL, so don't use a heater this time of year).
Sorry, I know this is getting long....
I'd like to know if I need to medicate him, or if this kind of wound will heal on its own, I just need to give it time and good care.
If I need to medicate...what to use??? I was worried the white color of it could mean some sort of fungus, but I don't know....
Please, any advice would be welcome at this point.
These are the pics - in order from when it started to now. The middle one was during the AQ salt treatment, before the lump burst. The last one was taken tonight...big hole, but no more lump.
