I have a basic idea of what i want to do with my tank. I basically want a low light, low tech tank for my 30 gallon. it will have 50 watts of light so itll be 1.66 watts per gallon. it houses an angel, a school of barbs and a school of tetras. the substrate is regular black sand. i think i wanna do a piece of wood with moss on one side and some rocks throughout the middle and right side of the tank. i was thinking java moss, valisnea, elodea and some crypts and anubius through the middle. any pictures or ideas would really be great. also what is a good trustworthy site to order plants from? please help!!
