my nano tank gets an awful lot of light, being in a corner window... everything got choked out by algae, except the plants are doing well... the Florida Flag fish eats algae, so I bought a small group of them to experiment with, they are in my dump tank for right now, with exception of the largest male, which i added to the algae filled nano tank... he seems to be doing fine, but it's too early to tell... if that doesn't work out, maybe I'll switch him out for a small female...
