All right, so I'm still working out just how I'm going to do the upgrades with my four (things have been a little hectic, so plans have been temporarily put on hold until things are a little more sorted). I've toyed with the idea of a sorority but have the idea that greater horizontal length is better for such a set-up, but now I'm thinking I might ask those with more sorority knowledge what their opinion is.
This is not to say I'll do a sorority rather than dividing the tank.
The tank in question is a 30-gallon Oceanic Cube which I would probably fill to, say, 20-25 gallons or so. I know that the primary keys to success with sororities is to densely plant them (particularly at the top), provide plenty of hides, basically break up lines of vision and provide plenty of options for escape, and have a minimum of 5-6 girls. I haven't seen anything mentioned about tank dimensions, particularly length, except that 10-gallons is, as usual, the minimum.
So...thoughts? Would it be better to wait to set up a sorority in a tank with more horizontal length? Or is it actually perfectly feasible to set one up in the cube?
Again, there's no saying that I actually would do a sorority yet, this is primarily out of curiosity.
