Unidentified Cichlids • Needing help Identifying my fish

[jigo]

I am quite new to taking care of cichlids, got these 3 guys from a pet store. All of them were listed as "Unidentified" and I am hoping someone can tell me what they are exactly. Here are side-view images of all 3 of them

Uh oh. The vertical barred fish is Metriaclima lombardoi a.k.a. Kenyi. The horizontal striped fish look like Melanochromis auratus. These two species are some of the most aggressive African cichlids commonly sold in the hobby. What are the dimensions of your tank?

The dimensions of the thank they are in is; l:30' w:1" h:18.5'

The tank is not big enough for the aggression of these fish. Can you swap out the fish?

For a 30" tank you will want to steer away from most fish from Lake Malawi.
