I'm researching to see what it would take to provide an adequate living area for 2 RES. I currently have an 44 gallon tank that looks just like this.

I know the equation 10 gal for every inch, but how fast do they grow???
Inch per year? or something like that. I don't mind getting a bigger aquarium but I probably won't be able to for another year since I will be moving.
