There is someone on this forum selling 12" cubes for 50 bucks. Smaller I know, but a good deal nonetheless.
Sounds like you have pretty much the same setup I'm looking to get so that's comforting. Will I have enough variability in what I can grow with one freshwater+ and no co2? If I get two freshwater+ lights will I be pretty much required to get co2? Thanks for the input!I have no idea why a cube would be a pain? I think they are the perfect tank for that. Active fish can benefit from long tanks but not sure why cubes are any more challenging to scape. I have a 150 cube as well and it's great for planting. The biggest drawback is lighting it as you may need extra shorter fixtures for front to back coverage.
