maybe some food that is labeled as semi floating. you could probably overfeed to the point to where all the fish get food, but I would be afraid of some fish eating till they burst lolSmall update:
What I thought was a molt amongst the amanos may have been a carcass! I have only found 3/4 the last few days. Although, they are good at blending in.
Noticing the glow lights do not eat at the surface the ways the other tetras do...not sure how to keep them fed, as the other (pigs) will likely get all the food before they do. I mostly feed mico pellets and flakes, which stay on the surface, with the frozen goodies just a few times a week. The frozen stuff sinks. Although, when the next 12 glowlights go in to this tank I may feed the frozen more often. Just hate to think some fish might overeat while others starve!
