Congrats on the babies! Mine recently had eggs but it wasn't fertile by the male. Maybe u should rescape your tank specifically for zebras if u like to see them more. I decided to dedicate my 150 just for zebras. So jts barebottom with just caves and a few driftwoods. very simple easy to clean and I get to see my zebras all the time. Update when the wigglers get bigger will ya!
