instead of stocking up on rockdwellers, you might think about adding Paracyprichromis nigripinnis; aka Blue Neon.
IMO daffodils are too agressive for that tank; all "brichardi" like cichlids spawn like rabbits, let siblings stay near to form family-groups with the elders and as a result form HUGE territories!
definitely a fish for a huge tank (75G, 100G, bigger) with sturdy tankmates (Tropheus, Lepidiolamprologus, Ctenochromis, Cyprichromis sp Jumbo etc)
leleupi's too are quite feisty with a fairly large territory, but it might work. Same for Neolamprologus cylindricus wich behaves exactly like that, and who should NOT be combined with leleupi.
Definitely add a few petricola's; as a 4-6 group they do much better and show up.
Easy fish to combine with Altolamprologus and petricola's inlude all kinds of shellies, like ocellatus, multifasciatus or brevis (those 3 are the best to start with)
again: put only 1 -ONE- species of shellie in that tank!
others are the smaller Juli's; Julidochromis dickfeldi, J ornatus or J transcriptus (but NOT J transcripus Gombe!). again; only a single Juli species.
Telmatochromis species are greatly overlooked and much easier and more peaceful than Juli's; T vittatus, T brichardi (most sold as "bifrenatus") and the new Zambian Telmatochromis are very nice. 1 species per tank.....
Juli's and Telmatochromis often quarrel, so best choose, not combine.
Aulonocranus is active and needs room to swim; iot's sandnest is family-pizza sized......how roomy is your tank? floordimensions?
Your tank can easily hold your calvus, 3-5 petricola's, a pair of Juli's or Telmato's and 6-8 Blue Neons (of wich 2-3 males, rest females). This way you have very different looking fish, and colors too (Blue Neons!)
best news: this peaceful colorful fish is an open water dweller and does NOT use the floor!
