Tunicate identification

Can anyone direct me to a website where I can type out a tunicate?
It was collected in the Florida Keys. It is reddish orange, and the surface is rough.
It is symmetrical, the siphons are the same size.
What size food do they eat? A spray of food sized for coral and feather dusters was violently expelled from a siphon.
