I bought my son a 29 gallon tank and am planning on replacing his 20 high. We aren't doing it immediately, so i want to start getting ideas. He would like to reuse the "bonsai" tree (for a fake tree I think it looks pretty good and the fish love to hide and play around it), the driftwood and the asian helmet. He will likely add something lego maybe aquaman or underwater ruins/ship..... He has asked to switch the substrate to black sand instead of gravel and would like to add some natural rocks. He would also like to make it a planted tank. He especially would like something tall to replace the orange glow "plant". I love to garden outside but do not know where to start in an aquarium. I would love some beginner low light plant options that would do well in a sand substrate. I am thinking not heavily planted to start with. Any ideas would be great. I want to be able to show him good options instead of heading to a store with no knowledge and making bad choices. And.@AngelTheGypsy I would love if you could give me your input as I know you have been working on your planting and 38 build. Thanks all!
