i currently have 2 discus in a tank by themselves. There about the same age and are about 12 cm in lenght. I have noticed them latley cleaning the sides of the tank.

How do i know whether there going to breed or not??

Sometimes its hard to tell but i've noticed three main events in my tank.
- In a community tank they will chase all the other fish away from one area.
- They will both clean surfaces in the tank i.e. glass/wood/rocks/breeding cone etc
- They dance around shaking and swinging there tails at each other.

i have noticed them scaring all the other fish from one particular place in the tank.
