Ok, so I have a really nice 55 gallon aquarium setup. I purchased it at PetsMart(way over paid on it) and got 100lbs of gravel, and well, 3-4 mid size decorations. I simply want to go with a more natural look. I have 10 cichlids, and a pecostamus( if thats spelled right) so I need to go with something they like. What do you suggest I do. I live in Texas, so I am sure I can find some rock, but what kind, and where can I find them? Would driftwood out of a river be good in this tank as well? I am trying to go the CHEAPEST way out - virtually free if I can just find the stuff. Please help me out!
