Hi and welcome to the forum
The blue and black striped fish could be a lombardoi or kenyi cichlid. They normally grow to 4-5 inches
The albina could be an albino peacock cichlid (Aulonocara sp). It's virtually impossible to tell what species an albino fish is due to it being white. Aulonocara species normally grow to 4-5 inches.
Both are from Lake Malawi and need a pH around 7.6 and a GH
The lombardoi (if it turns out to be that) is a real nasty bugga when mature. The peacocks are normally fine. Both eat meat but will take a bit of plant matter too.
