So, I posted a thread a few days ago: http://www.bettafish.com/showthread.php?t=204242&page=2
Regarding my male betta with a large lump on his side.
I'm trying to rule out it being a cyst or an ulcer, and have since put him in a 5 gallon (though only filled up to 3 gallons) hospital tank.
I have a small heater in there, an air stone, and some hornwort plant.
I filled the tank with water conditioned with Prime, though it didn't sit for very long.
I put in the Epsom salt as directed by LittleBlueFishlets.
However, I got a good look at him from the top, and noticed a smaller, but similar bump growing just behind his current one.
Could it still be a tumor to have developed so quickly? Or is it more likely to be a cyst?
I just worry so much about my little guy.
