i have 3 zebra danios in my 46 gallon community tank....i am new to this so maybe somebody can help me. one of my zebra danios is very very fat, it is round. i am guessing it is full of eggs. when can i expect her to drop these eggs? i have been watching this fish for weeks and nothing has happened. am i wrong to think it has eggs? also, im not sure the sex of the other two...perhaps the problem is that i have 3 females? i dont expect any of them to survive when hatched, but i am curious to see it happen. the substrate is large so it would be possible for some of the eggs to fall in between them.
