Hi guys, i got 3 cardinal tetras and recently notice 1 of them having a bloated belly.

I feed once in the morning daily and once a week i will give them frozen brine at night.

I did alittle search on this forum and dropsy came up but i check my tetra dun have loose scales or whatever.

The tetra never swim with the other 2 nowadays and hide behind plants and in 1 corner breathing very fast. All my other fish is fine and my parameters are normal too.

So is it really possible that she got knocked up? or is this some kind of tetra disease?
