I have 10 adult LSS discus in a 4 feet tank. They are about 2 years old. There are no signs of pairing up activities in the tank.
I know for sure some are females as they had spawned in the tank before. I only saw suspecting male fighting in the tank but no spawning/shaking activities.
Given the facts that they are mature fish, will they ever pair up and are there anything I can do to induce pairing activities?
Reply:
They should be matured in two years. Feed them heavily with live food for some time.
Change water daily. Observe them very closely. If they have behaved differently, like fighting, chasing, guiding a territory.
Take the pair out in bare breeding tank. They will spawn after some time when they adapt to the new environment.
You know for sure some are females as they had spawned in the tank before. They spawned but failed to guard their eggs, as the other 8 will eat the eggs.

what is the difference between male and female discuss and at which age we can find the difference
It is difficult to determine the gender, In general:
Size: 4in and above.
Dorsal Fin: Female Round, Male Pointed
Size: Male Larger, Female Smaller
We normally put 10 to 20 of the same age and let them pair themselves.
