I have a 75 gallon tank that I'm wanting to stock with tang. cichlids. Right now I have 3 Neolamprologus Pulchers, and 4 Altolamprologus calvus 'White chaitika'. I'm wanting to get a species of shell dwellers, and maybe a top dwelling species. I was thinking of doing Neolamprologus Signatus, but those are hard to find. Maybe some Cypochromis? If they eventually get too big, I can put them in the 200 with my frontosa. I need some help! :feedback:
