Hi thanks all for the replies. My tank has a fluroscent light aquarium blue, some rock and a bog wood and 2 artificial plants. After introducin the RBP's they were most of the time hiding behind a rock or under the bog wood and they seem to run at the sight of human movement. Is all this ok and can somebody direct me a to a site or gimme info here about their behaviours etc.
As of now 'am feeding them dried worms. Today was the first day and to jump start them I also introduced 2 mollies from my community tank and the Mollies are throwing their weight around and pushing the Natts little do they know that is due course they are gonna be FOOD. The introduction has pepped up the RBPs and one molly has already had a small bit of the tail fin nipped of in the first few minutes.
