I currently have 6 cichlids in my 55g and I'm looking to add another 5 or 6. How do I make sure they all have enough food? I'm starting to notice that a lot of my new life spectrum pellets sink to the bottom, only to have 1 or 2 of my cichlid eat them while the others watch due to the aggressiveness from the other two fishes. Should I feed in different places?
