since my fish died, i am now revamping my 40 gal tank for tropical fish.. so far it has black tahitan moonsand instead of gravel, and i ordered a bunch of cave kits and rock kits, and silk plants.. i got a new 70 gal filter, and some other decorations. this is the before pic, with no fish, once i get the supplies, i will take another picture.. then when i get my fish(which i havent decided on yet) i will post new fishy pics..
