Hello! I'm setting up a 20g-long. I wanted to tinker with the sand for substrate. How much sand is required for the bottom? I just put one 25 lb bag in and it comes up to the top of the black frame. Covered evenly. I have a second bag. I would like to put either a few small plecos, I love plecos, or dwarf bottom dweller type of fish. I'm open to suggestions, and if possible some sort of schooling fish, shrimp? .. I just want to put together something to where everybody is compatible. Plants as well. My filter is an aqueon quiet flow-50. Help set up my tank 😁 I appreciate the input.
