They cant.....

[Losi]

I bought three Pseudotropheus Zebra (Red)'s today and they are only about an inch and a half to two inches long, this evening I have noticed that one of my Pseudotropheus Elongatus (whois much bigger than the new intakes) has taken a likig to one of them and they both now have one end of the tank to themselves (the Elongatus) seems to be guarding).
Also the Elongatus is doing the 'Quiver' thing along a piece of slate and then the Zebra follows as if fertalizing eggs (there are'nt any at this point).

I have two questions really;

How big/old do Zebras have to be to breed and is it likely that two seperate types of Cichlid will breed?

Cheers

Yes, they can!!!

I have seen mbuna that are only an inch long with mouthfuls of eggs.
And yes, the various pseudotropheus/maylandia species can interbreed.

I don't think the size is an issue but I can't see an estherae mating with an elongatus. It is more likely to be a territorial dispute or a display of aggression. The quivering or twitching that you brefer to is more often a sign of aggression than a mating ritual, although it can be both.

You never know with Mbuna though!

If they are both males then for sure they are fighting for territory, but if you have a pair from each species it's possible for mbuna's to breed at a young age....

I dont think it is territorial as they chase the other fish away and then swim about together. The shaking is followed by the other fish following the same path over the slate as though fertalising??

Hi Losi ,

From what I understand, both the Pseudotropheus and Labidochromis are inclined to breed with their own relative species, i.e. Ps with Ps and Lab. with Lab.

To be honest, I don't know much more than that but have a browse through here.....

It's one of the best cichlid sites I have come across and you may find some useful info with the appropriate searches.
