I'd buy some taller plants (fake if you don't want the hastle) to ceover up the heater and the Internal filter. Looks pretty good besides that though. I like leaving alot of room for my fish to swim in and don't really like the densely packed tanks where you can't see anything in it. Looks good
Yeah the plants in the tank are just some freebie plastic ones, so hope to get some nice real ones to flesh it out a bit. I also have a background to put on as soon as i can find some tape.
