I've got a ten gallon tank that I recently refurnished. Natural colored stones, one large piece of driftwood, and large orange rock. Currently it's housing a male betta, 2 pygmy corydoras, a honey gourami, and a dwarf gourami. The betta displayed some territorial behavior at first, flaring and charging, but didn't actually make contact and settled down after about 24 hours. Now he only flares if they get close during feeding. The betta is dark blue and while the honey and the dwarf help I'd like a little bit more color. I was wondering if anyone has any suggestions. The guy at the pet store suggested smaller schooling tetras.
