I had the same thing happen to my danio. The danio after a while exsploded and look like popcorn. it turns out that sometimes they have swimbladder problems so you just see what happens cause you cant do anything.
Hi I was wondering if it is possible to breed a batch or two of guppies in just a 10 gal tank with dividers.
I could probably get rid of most of the first batch of fry before the next comes along.
