Hello ^^, recently I'm setting a new 20 gallon aquascape tank and my plan of tank inhabitants is like that: 10 harlequin rasbora, 2 bristlenose pleco a couple of snails (ramshorn, trapdoor) and 10 cherry shrimp. First of all do you think that it is overstocked? Second is I don't know how much food should I feed them, I'm planning to feed them twice a day and my food are: sera granugreen, new life spectrum small fish formula, ocean nutrition color growth & health formula, omega one immune pro, some betta granules from my old tank, and omega one wafers for my plecos, plus frozen-gell food. So lots of variety and all of them are granules, I don't like using flakes. So can you give me like you have to give them 15-20 granules etc. kind of answer? I know it really depends but I would appreciate a guideline better than 1-2 minutes rule. Thank you.
