My 75g is no different. It’s a mixed Tanganyikan tank that, at present, contains 5 different species of cichlids (A. calvus, N. leleupi, T. vittatus, C. macrops, J. marlieri), three species of dithers, and a couple of species of bottom dwellers. The tank boss is a male Altolamprologus calvus, one of three calvus in the tank (2m, 1f). However, I’ve discovered that the tank has an associate tank boss…and it’s not a calvus.
Below is a photo of the associate tank boss. What he lacks in size, he makes up for in tenacity. He just generally has a bad disposition. As far as I can tell, he hasn’t really carved out a territory. He just roams the tank doling out cichlid justice to pretty much anything that crosses his path. He’s not killed or injured anyone yet, but he’s certainly sent the entire population in a panic when he zeros in on someone…except the boss calvus.
