Fibramia thermalis

Fibramia thermalis, commonly known as the Half-barred cardinalfish, is a friendly schooling fish very similar to the more well known Zoramia leptacanthus. At first sight they may look a little dull colored with their almost see-through body. But once these fish acclimate to your tank, their fins will devellop a beautiful purplish edge.

Besides their color, these fish are very interesting to watch, because they're one of the few small schooling fish that always stay close together. Usually in a place with little flow and light, like beneath a montipora plate or overhanging rock and they come out when light is dimmed. An easy schooling fish for the beginning aquarist.
