Them horny little poopie monsters!

Ive noticed 3 of my 10 Danios are knocked up!
Is it the time of year that could be causing this?
Where do they usually lay their eggs? I know
one of the danios has given birth already but
I didn't see where she layed the eggs. Imma
keep a lookout for these babies! BTW I could've
sworn one of my leopards was a male but I was
apparently wrong. I was looking for "him" today and
couldnt find 'em but the head count was right on.

Didn't recognize "him" with the preggo stomach!!!
...maybe he got a sex change

They are egg scatterers so the eggs will be on plant leaves and whatnot, don't know if you will be able to see them. Since it does not look like you have catfish other than the otos, maybe something will come of it - good luck!

Danios will probably eat and eggs they can get their hands on. If you're lucky a few eggs will fall into the substrate and you'll have babies. But danio babies are REALLY tiny, and they need to be fed liquid food for a while. If you really want to breed them properly, use marbles as substrate in that 10g and put the danios in there. Once they lay thier eggs you can take them out.
