That's his swim bladder. It helps him maintain his buoyancy in the water. As long as he's active, energetic and able to swim up/down whenever he wants -- he's fine.

I'm thinking that you may be noticing it now because he's probably grown since you've gotten him. Often, the fish at petstores aren't fully grown yet. So as he's growing, his swim bladder is growing too. It's probably noticeable on him because he's a light color.

My only suggestion is that you increase to 50% water changes every week. Even though there's a filter in the tank, wastes and bacteria can build up over time. Doing a 50% water change will help remove them. Increasing the amount of your water changes never hurts, and very often helps them remain healthy.

AHHHH OH gosh thankyou so much!! I was worried cause I could only see it on one side and it looked kind of uncomfortable for him (Cause its more that tiny lump towards his actual tail rather than his body) but he seems to be 100% okay and he swims around like mad & eats every day without missing a pellet (though he's very aggressive when he does!)

but gosh thankyou this put me at ease & i will take up your advice on the 50% water changes too :-D

I just went through the same thing with one of mine, actually! Saw the same thing you're describing on an otherwise healthy, hungry, and active fish in a tank with appropriate water changes/testing- got a little worried, but it's been a week or so since I originally noticed it and my guy seems to be fine.

I test water every 2 days (API Master Test Kit, track on an Excel spreadsheet) and do partial water changes of around 50% every 4-5 days for this guy.

He looks like a real beauty uvu but glad to know i'm not the only one c: i guess i'll just keep an eye on it in case it looks obnoxiously big or something c:

I am just curious, is this actually the lump you're talking about? The picture isn't terribly clear when enlarged, so I can't see if there is for sure something there where I put the arrow, but if that's the lump you were asking about, that's not the swim bladder. It could be several things though, none of which you necessarily have to worry about right now.
