Currently have 5 zebra danios in my 19 litre tank. No other fish. When I got them I noticed one was fatter than the others so did some research and reached the conclusion that one was female. It's roughly 4 weeks on and she's gotten bigger but today I also realised two of my other danios are getting really fat too. They all behave as normal and all are eating fine. All the fat danios seem to have a slightly paler colouring too. Are they just carrying eggs or could they have some sort of illness or parasite?
