Just want to share with u guys, mandarin fish will keep pecking for food as long as they are awake. if your tank has no pods, u have to keep feeding it almost every hr. i was monitoring my pellet and mysis eating mandarin by placing them in container with just a pc of LR. i tried feeding once in the morning and once at night. although they ate alot but still their stomach sunk in after awhile. This show that they really need to eat alot. maybe got to use food timer. and since they are slow eater, u cant keep with other greedy fishes.
