I'm updating this thread, as my situation has gotten worse
After the Epsom salts treatment, I floated Indian almond leaves in the tank at all times, and (on the advice from a guy at petco - note to self....DON'T take advice from the guys at petco! - Although I'm sure he meant well) he said to not do 100% water changes as that was what probably caused the stress and the lump....I bought a gravel vac and for the next 2 - 3 weeks, just changed 50% of the water every 3 or 4 days, using the gravel vac. All his water changes, had the IAL soaked overnight.
Anyway...after a few weeks, I suddenly noticed he was getting fin rot on his top fin! I immediately changed his water 100%, took out ALL the gravel, went and got AQ salt and have just finished a week of AQ salt treatment. (1 tsp/gallon) plus stress coat, changing the water 100% everyday for about 8 days. (He's in a 2.5 gallon, but for treatment I just used 1.5 gallons.) I use Reverse Osmosis water plus "RO Right" minerals to add back some minerals to the RO water.
So now the poor guy has this lump, which has not got better from the IAL, plus fin rot.
I feel awful!
After the AQ salt treatment, the lump has turned white, and grown - see picture. Does this mean anything? It was blue before, like the color of his scales... if you look at the previous pictures.
It almost looks like I could scrape it off, but I dread to do anything like that.
anyone have any advice!
