Bascic Care – An extremely colorful species. The pictures don’t begin to show the true coloration. Males and females are colorful, males have a distinguishing hump on their head and most females have a black line accross the bottom of their lower fin. Not too picky about food, and not overly aggressive, although they do a lot of fin flaring and mock fighting. This is a very beautiful and attention getting fish. They stay mainly around the bottom of the tank.

The males humphead can be seen clearly here.

The male, trying hard to impress the female, who is trying hard to ignore him.
For now, anyway.

My Peacock Gudgeon Tank. they love the PVC “caves”, but mostly ignore the coconut cave.
Volcanic rocks are added here for decoration and as a very beneficial aide to filtration. The volcanic rock acts as a nitrate removal system like the more widely used “Live Rock” in saltwater tanks.

The peacocks have proven to be easy to spawn with the pvc “caves” and the fry are extremely hardy and easy to raise with the one exception that they refuse all non-live food.
