my pepperd cories are turning mostly black and its awsome. im pretty sure its cause their substrate is black sand but these have become the coolest fish ive seen. any other fish change color based on substrate. i know some change cause of moods like oscars but i never seen ones than change due to substrate .
take that back i thin stingrays do that too\
they look awsome though .
