I recently bought a mixture of Leopard and Zebra Danios from an aquarium supply shop and have now discovered an altogether different fish was mixed in. To me it appears Danio shaped for want of a better description, but it has the most amazing and pronounced lumious spots from head to dorsal fin, a same colour stripe from fork of tail to part way along its body and an eye circle the same colour. These are all irridescent pink at the right angle in the light. Any ideas before I travel back to the shop? TIA
