A lot of this is fresh in my mind because I'm just getting in to the hobby myself and pruned my rotala for the first time yesterday, lol. I transferred some sprite myself a week or so ago into my wife's beta tank.

That 26 is gonna look NICE planted!! Update that thread you linked here to keep us up to speed on what you do with it. I'd LOVE to have a tank that size with those dimensions.
