i have 4 eba in my community tank i have noticed that 2 always seem to be in the same part of the tank I cant tell if they are male or female but the darker part of their face is black while the other 2 is a light grey actualy while typing this possibly the female is shaking against a plant and what looked like eggs fell of the leaves and she collected them in her mouth they have only been in there 3 weeks I think I have answered my question ha ha
 
Eggs shouldn't be falling off leaves a d if the fish collected them in ita mouth they were. The acara shake the leaves and then lay on a hard surface. They are not mouthbrooders. But it does sound like breeding behavior.
 
Many of the Acaras deposit eggs on leaves, so that the leaves can be moved around if danger approaches.
Some believe this is a prelude to the evolution into mouth brooding.
You can sort of see the Andinoacara coerleopunctatus eggs on the leaf below, but they are very well camouflaged and the leaf was in the back of the tank, so hard to get a clear shot.

ok well other 2 acaras and a female krib are the other end of the tank my female krib who was the boss of the tank is very nervous going any way near the right hand side of the tank they dont seem to see the tetras as a threat
 
That sounds about right as well. When my blue acara(not electric) spawn any other cichlids are driven away. Tetras and cory cats are allowed within a few inches of the eggs/wigglers before they're chased away
 
the thing is they are very young the bigger one which I think is a male is just over 2 inches in length while the female is 2 inches it is facinating watching them though
 
Size differences in mated pairs are common in many cichlids.
This mated pair of sajica I had around 6 years ago is a good example.

same (although not quite as drastic), with the pair of cutteri below.
 
well there are fry in the tank the thing is my female ktib keeps probing the area where the fry are the female is defending them but not the male

Yes I personally had female Kribensis that actually killed a male after the eggs were fertilized. The female also protected the fry alone after spawning with a different male.
