The picture above looks like a white cloud. White clouds are very docile, small, cooler water fish. They grow to 1- 1.5 inches long and need a few gallons per fish. They are a melange of brown, green, yellow, red, neon blue, and black. Their red can be particularly striking on their lips and caudal fins.
White clouds are native to streams in Southern China where they are now thought to be extinct.
They live for 3-10 years. I had a pair that I bought in August, 1995. The female was still active and breeding until her death in 2000. The male developed cataracts before his death in 1999. The female always looked like she is ready to burst with eggs.
