I am new to the hobby. I have a 200 gal tank with 2 fish - a 2" clown and a 1.5" damsel. I don't want to buy a lot of expensive fish, only to see them die due to my newbie mistakes. I'm using "Omega One whole Seafood Protein Marine mini pellets", as recommended by petco fish persion. The jar says "feed up to 3 times daily, using only enough food as your pet fish can consume in two minutes". Well this is a huge aquarium for 2 fish and they don't even see the pellets. They sink to the bottom pretty quickly. I fear they are not getting enough, but don't want to overfeed either to prevent nitrates. The damsel hides all day but comes out at night, so I drop about a dozen pellets in front of his nose and he eats a couple before the rest sink to the bottom. Same for the Clownfish. Advise?
