My pl*co is changing colors. Is this normal?? Right now he is Black, Light brown, and dark brown??? He is in a 10 gallon for now till he is big enough to put into a 55 gallon...
most (all?) fish change colors when stressed or startled
or is the new color permanent? hes black, light brown, and dark brown...what were the colors before? how have the colors changed exactly? just in brightness?
