ok, so i've taken the remaining fry home as i figure they likely have a better chance here where i can have full control (i only work part time at the shop).
i'm feeding them "fry bites", which is a tiny little floating pellet/flake thing, but i'm not sure if even that is too big for their little mouths. they've obviously been eating something over the past week, but not sure if this is the best for them - what else can i feed them?
also, there's about 20 left, and they're in a small (15cm cube) unfiltered betta tank with a couple of small snails (the snails have been living in it for months, so it's to some degree established) - how often should i do a water change?
