Clown loaches x20, some peaceful cichlids, Flagtail, couple of plecos, blue Botia loach, yo yo loach, archerfish. All the overcrowding of the bottom dwellers esp the crazy loaches caused the morays to hide a lot for the first 5 months but once they started routinely eating from the surface they stopped hiding all the time. They definitely can aggressively fight their way to floating food with the loaches, gorge themselves for 2-3 minutes. Sometimes they even snatch krill out of the mouth of the loaches. I feed 5 days a week, though they would eat everyday.
