Update. This was "tank day" so all the smaller tanks were refreshed. Pothos cleaned and added. Very calming to all the tanks! Some of the fry are picking at the roots. My goofy parrot Tango swam upside down before tangling himself in the vines. In the growout the older fry are much calmer and have 'disappeared' instead of swimming in frenzy at the front all day. In the 125 the renegade fry are swimming off the floor and among the roots. Cools tuff.
I'm going to need more pothos, though. Didn't have enough left over for the 125 and ran out before I could put any in the 225. Will look on ebay for less expensive options.
