Also known as "The Peacock Goby", and "The Rainbow Gudgeon" Latin Name - Tateurndina ocellicauda

Spawning - Cave Spawner, males will guard the 30 or more eggs which will hatch in 5 to 6 days.
Fry Care - Fry need to separated from the adults, they can be started on baby brine shrimp and/or microworms.
Basic 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.

Peacock Gudgeon Tank
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.
