I have a 36 gallon bow front aquarium. Its dimensions are 30 in. long, 15 in. wide, and 21 in. high. I just bought sand that doesn't affect water chemistry. I plan on heavily planting it with a pH of 6.5 that I will modify the water too. I plan on getting 4 angelfish, 4 clown loaches, and 12 black phantom tetras. Any comments or suggestions on this idea?
