Still going great. All 8 are still getting along. Maybe the 2 that died were weak from shipping and the others sensed it? I added an aqueon powerhead to go with the larger sunsun powerhead which really got the water moving. Also I got an order of 5 anubias and 2 bolbitis that I plan on trying down tomorrow. I'm looking to get a few more buffaloheads soon, now I think I have a male and sub dominate male.
I really wish I could have done a nice river manifold setup, but the tank was already stocked and running when I decided to go this route.
