A homocercal tail is a caudal fin composed of two lobes of equal proportion. Homocercal tails are the most common caudal fin type in fish but can come in many symmetrical shapes. A homocercal tail is contrasted with a heterocercal tail which has unequal lobes. (fishionary.fisheries.org/homocercal)
The Rose Fish has an even-lobed homocercal tail.
