I am setting up a 55 gallon tank for a friend who's son has Downs, he really enjoys watching the fish but the family doesn't have allot of extra money. I have everything needed to set up the tank but some kind of top/lighting. Doesn't need to be anything to fancy just enough for some low light plants. I don't have allot of extra cash to throw at this so if anyone has something cheap,free or something to trade for let me know!
