looking good, glad they all get along, lets hope its lasts, don't see why not really.
they still haven't coloured up at all really, but they did take a week or so to settle in my tank so its expected really, they go a dark colour with yellow/orange markings, and they look stunning, they look good all together, more friends to play with!!
i only had sand in my tank which as you might guess, is a pain in the bottom keeping clean but as you say even pebbles should look good and help them feel more at home.
