That light looks crazy, care to share the details of it? I'm going to assume plant friendly is required on this one. I'll assume upgrades aren't feasible for at least a number of years. With all of this in mind I'll throw a suggestion that I'd personally like to try some day, so I can live vicariously through you until then. I would suggest qting some livebearers and treating them for any diseases that could be a problem, and then dumping them in for a couple weeks. After you seem that their are too many I would throw in a few pairs of dwarf pikes, crenicichla, in and appreciate the experience. Not sure if this is possible without compromising there desire to eat pellets, but they will run out of feeders eventually. When that happens I'd add one of the bigger tetra, probably black skirts or whatever is available. That said, I'm certainly not an expert in the like world so I would consult one of the like experts. There's a fair number of these guys here, I would page them if I wasn't on mobile.
