Congo Tetra, Torpedo Barbs and Pentazona Barbs decisions in a 200 litre tank

[Byron]

I went to my local fish acquatics to purchase the pentazona barbs but unfortunately they were out of stock for 2 weeks. I was taken aback to see the Keyhole Cichlid fish. Never seen them before but fell in love with them. Wanted to know whether these species will fit in my set up or not and if so how many i can stock up. Can I later introduce the pentazona barbs with them as well??Just curious

The following data may help. A pair would be best, though this species is monomorphic, showing no external differentiation between male and female.

Compatibility/Temperament: Very peaceful except when spawning. This is a very shy and retiring species, easily frightened and should not be combined with other more aggressive cichlids. Peaceful characins, rasbora, and substrate fish are ideal as "dither fish" to lessen this species' natural shyness. In larger tanks, it may be combined with discus, angelfish and some of the dwarf cichlids.

An ideal cichlid for a community aquarium of non-aggressive fishes. Kept on its own, it will likely be very shy and retiring, and prone to stress. The presence of other fish (termed dither fish) will keep it more settled and relaxed. This is certainly not a fish for a barren tank, in which it will be highly stressed.

Size: Some sources report up to 5 and even 6 inches, but most suggest 3-4 inches as maximum in aquaria. Females are normally slightly smaller than males.
