After tax returns I'm planning on adding another aquarium. I'm debating on the two because they essentially cost the same at the LFS. The tank will be housing frontosa, likely 12-15 of them. Which do you think would be better suited to a colony? Dimensions I believe are 72" x 36" x 27" on the 300 vs 84" x 24" x 30" on the 265. I very much doubt that I'll be adding anything aside from the fronts. Thanks for any thoughts.
