The parent pair are still what I consider very small, and young, only about 3".
Although not particularly aggressive when not spawning, they become very diligent parents. The first time this pair spawned, they were housed with a belly crawler pike, that they kept on one side of a 50 gal tank.
The other day when they put down the plaque of eggs from this spawn, had a Paratilapia sp "Andapa" as a tank mate, almost triple their size, and easily backed it away from where the eggs were placed.
I have, of course, removed the Madagascan.
I saw the parents of my breeding pair of Geos the other day, they were about 6"-7".
From what I have read, iporangensis remain slightly smaller than normal braziliensis, but don't know that from personal experience.
