Cory fry week 2 in a bare tub, how long before you add any substrate?
Pic below of the two week old sterbai fry in a bare bottom tub with a sponge filter and some leaf litter. They're eating crushed flake and microworms fine. Do you keep them bare until they're an inch or do you add sand sooner? Worried about barbels but also about how much waste builds up on bare glass.
