Symptoms and Treatment
How has your betta fish's appearance changed? Split tail fin, loss of color, his back right side is pouched out a little, like there is a lump under his skin. This does not look like dropsy, since its not his rib cage that's bulging slightly, and he doesn't have the pine cone appearance.
How has your betta fish's behavior changed? Just floating at the top, not really moving. Today he wasn't able to swallow his pellets like he used to be able to.
When did you start noticing the symptoms? The visual symptoms just started today, but the floating doing nothing started as soon as I got him his new home last Monday.
Have you started treating your fish? If so, how? I've just added nitrifying bacteria to the tank to help just in case.
Does your fish have any history of being ill? Just bought him, so I don't know.
How old is your fish (approximately)? Just purchased from Petco.
I purchased a Betta, and after reading about them I bought him a 2.5 gallon home with a heater. The day after I put him in his new home he took ill! I treated the water, so this shouldn't be an issue. I took a sample of the water to Petco for them to test, and they said that all the ranges were within normal. I bought some Microbe-Lift products to help start bacteria and then the one specific for nitrifying bacteria just in case.
But this morning I came in and his tail fin is split, and he can't seem to swallow any food like he used to be able to. His back right side is stuck out, like he has a lump under his skin, so I thought it might be swim bladder decease but the pictures of fish with it don't seem to match my fish. He doesn't have ich, and I don't see any other parasites on him.
Is there anything I can look for, what can I do to help him?
