Some Info On Keyholes, Any Ideas What They Are Doing?

[Dan-CR4]

I got two keyhole cichlids and now and again they sort of put all there fins up and like get a bulge underneath the mouth that goes up and down. its really wierd they have done it for ages, just wondered what they are doing.

there does not seem to be any aggression with the keyholes and my tank is rather peaceful unless the bolivians square upto each other, but thats not often.

that's just them flaring. It's soft of a dominance thing. All my cichlids do it at each other from time to time when somebody is getting too close to their territory or otherwise.
