gah! Maybe I should take some tops from my 30gal? That one is doing PERFECT (if not too perfect heh) Ill bring a bundle from the home tank that is nice and fresh and i spose that would be a good way to test for deficiencies and things of the sort?
might be time to clean it out and do some replanting
Also, did you mess with the ones your brought to your work tank, like root trimming? We often times think this plant is a super plant (it really is), thinking we can do anything and it'll still survive.
