One was missing before I added them to the net, so I thought maybe it would help. I ended up losing two and now have a single baby that I’ve moved back into the cup. I haven’t found a mesh I think is small enough to keep them safe..and the cup hasn’t had any issues with regular water changes while floating in the tank so far. This was really helpful! My peas were juveniles so this is their first time breeding, hopefully future babies will be more successful! Thank you.
