Here is a brief video my mature pair of Inca Stone cichlids. The 90G tank is too busy for them to successfully put down a spawn. They are in with a mix of Chocolate cichlids (6), Caquetaia myersi (1), Thorichthys pasionis (4), and an exCichlasoma ornatum. When they do spawn, they will lay their eggs on a 'portable' object (leaf, thin piece of slate, small piece of driftwood) and then proceed to haul it around the tank. Once the eggs hatch, the parents 'mouthbrood' them. A very interesting adaptation ... very much like the Bujurquina genus.
