So I just recently bought a Dwarf Gourami (male) from a petstore... He's pretty big! I have in in a 15 gallon tank (alone) with LOADS of plants that he LOVES to eat. But how many flakes should I give him??? I don't know how many I should put in the tank. I have TetraColor Tropical Fish Flakes Picture this... Look at your thumb. Say each flake is the size of your thumbnail (without the white tip on the top.... Just the pink part of your nail). How many flakes that size would you feed to a Male Dwarf Gourami (abt 1.5-2 inches in length)? And yes, I know I rub the flakes between my fingers before I buy them in the tank so he can eat it.
