It started as a shell dweller only tank, but I wanted a bit more color so I added two mbuna as well. The tank is a 20g (long variety). Substrate is Eco-Complete African sand which is very nice and has the water pH and hardness perfect with no effort from me. It did take a few days for the cloudiness to subside. I have some cave-filled lava rocks along the back wall and two corners. I also bought an assortment of shells from I got 4 Neolamprologus Multifaciatus (admitedly adorable fish, only about an inch long right now. They are spawn of a wild caught pair according to the seller). Hopefully I have a mix of sexes, they are too young to tell. For a little more color, I got a young yellow female labidochromis who so far has been very chill and non aggressive. I also got a young M. Lombardoi "Kenyi", which is very attractive but I have since learned will get too large for me, and it has been a little boisterous in the tank. I want to find a fish with a more subdued attitude and blue color to replace him. The shellies have started to check out their shells, and for a little 20g cichlid tank its a lot of fun to watch!
