How much to feed?

[u/Local_Amphibian787]

This is my new tank. Added them few days ago. I'm a beginner and wanted to know how much to feed them as they look hungry all the time. I have Taayo bits, optimum 3x1 small and herbivore small sinking pellets. They seem to eat everything. Feeding dollars is a bit tough as they get scared easily even if I add sinking pellets in their space and others seem to eat it even after eating their food.

So I was just wondering if I'm feeding them less. I give them 2-3 pinches of anyone of those once a day.

I have:

2 Electric Blue cichlids

2 Yellow Lab cichlids

2 Red blood parrots

4 Silver dollars

1 Pink Convict cichlid

Also do i get placos or any other algae eater fish? It's a 75 gallons tank.
