Well, I have not received the Pao Baileyi as of yet. It should be arriving this week. So not sure of its size, that's why I was thinking blood worms. I have lots of baby guppies that should give it some exercise. But I will want to provide it with a healthy diet. I also have a tank full of red tailed Goodid. They are similar to your Limia vittata. They have large young that are not eaten.
He will go into quarantine as this tank cycles. My guess is around September it should be ready. I do not like to introduce new fish to a tank until it starts to establish some algae growth . Water perimeters all look great for now, but its only been a week.
Wish I did get a group now. Oh well, maybe later.
I will keep you updated and provide photos once established.
Congratulations on those fry. That is so exciting !
Cheers
