I've recently discovered rainbowfish. I visited my fishy store about a month or so ago to pick up a dwarf gourami. They had them but they were sick so couldn't seel them. They persuaded me to take home a couple of dwarf rainbowfish instead. It's taken a couple of weeks to bring them out of their shells abit, but I've done my research, added another female and they have really started to shine. We have the courtship nose flashing every morning when the lights come on, it's brilliant to watch, like a car headlight being switched on and off! I intend to slowly add a couple more in the coming weeks as they need to be in a larger group.
