i've heard of it before. I think its called "bloat". I thinks its pretty much incurable. Contagious, im not so sure. This is almost exclusively in danios. Good luck

How many danios do you have? Are all the danios like that? Sometimes females can look bloated like that if full of eggs.

It could also be constipation and you might try feeding the danio a little bit of crushed pea (a peeled and thawed frozen pea if possible).
