Right now I have 2 featherfin catfish, 9 neon tetras, 3 gold barbs, 4 penguin tetras, 1 blackskirt tetra and 1 painted tetra. I just added 9 Glolight tetras. I'm planning to double the amount of neons and glolights, and add 4 or 5 more gold barbs. I also want to find a top feeder or a pair of them. I'm open for suggestions!
