OK, I finally got some new pictures. I had to move the tank to a more shaded area of the balcony because the sun was heating the water up to almost 90 degrees F and it isn't even summer yet.
I've currently got R. rotundifolia, H. polysperma 'Rosanervig', P. stellata "Fine", P. helferi, Nesaea sp. 'Red', Alternanthera reineckii 'Sunset', Glossostigma elatinoides, Hydrocotyle leucocephala, Hydrocotyle verticellata, and Ranunculus papulentus growing in the tank. All are doing well, thriving even, and the only algae issues have been dust algae on the glass that scrapes off easily. The plants simply love the natural sunlight
I apologize for the quality of the pictures - it's almost impossible to get a picture without reflections because of where the tank is located. I will try to get some better shots at dusk tonight, although it will probably be snowing at that point :P
And yes, those are bubble-eye goldfish. I call the one on the right side of the first picture 'Popeye' because one of his bubbles popped on something in the tank, but should grow back in time
