Compatibilities (Mbuna Cichlids)

[lucky777ca]

I was just wondering if the following would have any compatibility issues:

Pseudotropheus saulosi
-> Looking like females (some of them with somewhat brown barring?)
Metriaclima estherae
-> Looks like 2 males (Red variant), all others are females (1 cherry red, 1 minos reef)
Metriaclima callainos
-> for sure, larger ones are females
Melanochromis parallelus
-> supposedly one male in the group
Gephyrochromis lawsi
-> seems to demonstrate spawning behaviour, with one of them shaking in front of another fish, and they are only 1-1.5" in length.
Labidochromis hybrid
-> I'm not sure what, looks like an Electric Yellow, without the black bar on the dorsal fin

I haven't seen any M. parallelus and G. lawsi here. Would it be safe to assume that they are somewhat uncommon here?

Thank you in advance.

Tank size, parameters, filtration, etc?

[lucky777ca]

Tank Size: 90G
Dimension: 48"Lx24"Wx18"H
Filtration: 2 x Fluval 404

Inhabitants: 5 Gephyrochromis lawsi, 5 Pseudotropheus saulosi, 5 Metriaclima callainos, 1 Labidochromis hybrid of some sort, 1 OB Red Zebra, 4 Melanochromis parallelus, 7 Red Zebra (1 'Minos Reef' Female, 1 Cherry Red Female, 3 Red Females, 2 Red Males)...

Setup: Many caves, some egg crate dividers so that the smaller fishes are able to get to safety... (although the larger ones just found a way to get to the other side).

Sizes: 4 of the 7 Estherae, 2 Callainos, Labidochromis and OB are pretty much the only large ones (3-4"), while the other fishes that aren't included (saulosi, lawsi, parallelus, 3 of the 7 estherae, 3 callainos) are less than 2.0".

Parameters: 0 ppm NH3 (Ammonia), 0 ppm NO2+ (Nitrite), 15 ppm NO3- (Nitrate), pH 7.6

Should be fine. The only problem I see is the Callainos and Red Zebra cross breeding. Also watch out for male dominance.

[lucky777ca]

It seems like the male M. estherae are leaving the callainos alone. The M. estherae have already spawned a couple of times now.

I assume that the two larger callainos are females. That might be the reason for non-aggressive behaviour towards the callainos. I was hoping in getting at least one male in the last purchase of M. callainos.

Hopefully, they will leave them alone. If not, then I might have to remove one of the two Metriaclima species.

Thank you, tarheels910.
