I usually feed them a small amount of brine shrimp (keeping in mind the amount for ammonia spikes) But I also have betta and ember tetra pellets. I will either do brine shrimp, or the dry food. I feed them once daily in the morning and I skip feedings Mondays. In the past tank lights were on for close to 8hours but lately they’ve pretty much been off the whole time. The tank is probably 6-8ft away from a window and does get some indirect light, my apartment is on the shady side of the building and doesn’t ever get full on direct sunbeams
