Thanks for all of the replies and advice! Tank is doing great so far. I haven't added anything new since before Christmas. To recap my fish stocking, I have:
2 Keyhole Cichlids (2 males I think - tussle with one another every now and then, but no damage)
3 Pairs of Black Phantom Tetras (very fun to watch, the big female seems the most aggressive but the males are growing and starting to look impressive)
6 Green Corydoras and
1 Albino Bristlenose Pleco
So, I have 15 fish. Do I have room for a few more? What would you guys suggest? Something unusual would be cool. Thanks!
