i just recently got a 180 gallon acrylic aquarium with a built in overflow for $200 and its in good shape. i just had to buff out a couple scratches. so all my stuff is on the way that i ordered. ( filter, pumps, heaters, powerheads and so on...) i really dont know what to do as far a decorating. its so big. i have 4 oscars a pacu. a bala shark, a catfish, and, 2 convicts i will probably get rid of. the tank has a black background and i bought a brownish red amazon gravel and if anyone has any suggestions on decorations or moss i should use that would be great. i also am going to be using a 20 gallon freshwater refugium and want to know whats best to put in it as far as plants and maybe some fish. so if anyone has any suggestions.... but other than that i think i got a good deal on the tank, no?
