My tank is a 37 gallon tall that consists of fluorite substrate and pea gravel on top, with amazon sword, dwarf sag, and anubias along with Malaysian driftwood. I dont dose with anything. I have fluval LED lights and a hang on back filter(I believe it's Aqueon) I have 9 zebra danios, 2 CAEs, and a bristlenose pleco. I know I need to return the CAEs when they mature, but overall what should I do differently to make my tank better, or do in addition specifically?
