I have wild cought Chocolates (Hypselecara temporalis) and they are no different from captive breed ones, however there are some subtial differances in coloration from collection point to collection point in wc chocolates. So depending on the collection point some races may look different from others but that's about it. Thay do, as has been mentioned change coloration with mood changes. Mine go from dark brown to rusty to green and all shades inbetween as they change moods or are in breeding dress, submissive fish also present different colors from dominat ones.
