Dinner, Lunch, and Jack (the one-eyed tilapia) are doing well amongst the minion. I'm sure they get the best morsels too.
If you're an aquaponics nerd, you might find this info interesting ... pH is 6.8, ammonia is negligible, nitrites 0.25 mg/L, and nitrates 15 mg/L. I dunno the dissolved oxygen but I use an airpump and airstone. Oh, and the PVC pipe with holes that is running along the bottom of the tank is part of the pump, drawing off fish solids (i.e., poop). It's been really effective so far!
