I have glowlight and ember tetras. I currently feed them Repashy gel food once a day (when I turn their lights on) and I take the food out when I notice that their stomachs starting to bulge a little. They seem to be doing good right now, but I'm wondering if I should also start feeding them at night at well, as they seem to digest the food pretty fast. I'm leaning more towards no, as I'd rather underfeed a little bit rather than overfeed too much. If I were to feed them at night, I'd probably feed frozen brine shrimp instead of the gel (I'd do 1/8th of a cube, so just a little bit). Thoughts on this? How often do you guys feed your tetras and how much do you feed?
