What size tank are they in? Are they the same type of clown, were they introduced at the same time, are they the same size?

When was the 2nd clown introduced? How big is the tank?
I have 2 pairs of clowns, the pair that were there in the tank first would chase the 2nd pair and try to butt them away from their area.
After a week of the new pair insisting on being near them they started getting along.
After another week the new pair claimed their own area in the tank. So now i have 1 Pair on the left of tank and 1 pair on the right of the tank.
