Well last night I got 4 zebra danios for my 12 gallon tank. I've noticed 3 of them have developed much more fatter and rounder stomachs than when I got them last night. I could tell the 3 were females however when I bought them because they were arlready a little rounder in the belly. And also the one male is fine so I'm not sure if he's just a player or he hasn't gotten sick yet if its a disease. What do yall think?
