Set up in 80 x 35 x 35cm tank

These cute little whiptail


This is a parent candidate, still in mix size..
I have tried to raise the fry.. Only 100 of 1500 alive up to 2"

It's so hard to raise.. I read about earthworm sticks, but the seller is not shipping to Indonesia..
Could anyone give an advice how to make that earthworm sticks?
