Set up is 54l, cycled, planted, 9 cardinal tetras (I added three yesterday) and 5 gourami. The tank has been ace, no fluctuations of any sorts. The fish are fed flakes and the occasional sprinkle of blood worms. Three of my cardinals are noticeably rounded, they aren't pregnant cos they aren't live bearers, are they constipated? I dread to think that they swallowed the blood worms whole....
But as the others said it is most likely there full off eggs.
