Bloated congo tetra?

[grace130994]

Recently got a couple of Congo tetra, they both seemed fine but then I noticed that the male was getting a ballooned belly... It's weird as while sitting watching him you can see it get bigger, smaller, move from right to left, even split into two lumps... Then sometimes it completely disappears... It's almost as if there's something inside of him!! Please help!!


From the photos you can kind of see how the lump differed in sizes, they were also all taken in the space of 20mins or so

Had you fed him shortly before you noticed the lump? One of my danios gets a lump similar to this after I feed them, she's a pig and eats most of the food I put in

Yes been honest I think it is mostly after feeding... I just got worried after seeing it moving, mind you he is very greedy! Thank you

No prob Just keep an eye on him, if it only happens after feeding it's probably because he's eating too much. You could try cutting down the quantity of food you give them and see if that makes a difference too
