A relatively stocky, oval body shape characterizes triggerfish. Their caudal fins are quite small, so these fish rely mainly on the rippling movement of the rear part of their dorsal fin, combined with their anal fin, to propel themselves through the water.
Closely related to the triggerfish, filefish are not so boisterous in aquarium surroundings as their cousins, nor as destructive. Most species are smaller than triggers, but they share with them the split configuration of the dorsal fin (the first part forms a spine used to anchor the fish in a cave). The ventral fin on the underside of the body is similarly modified, providing additional support.
The elegant swimming motion of these fish has been likened to the flight of butterflies fluttering around flowers in the garden. As with their insect counterparts, butterflyfish also tend to be brightly colored, making them an extremely popular choice for the home marine aquarium.
Wrasse are lively, active fish found in most warm seas, though the majority come from tropical waters. They tend to be colorful, displaying elaborate patterning on their bodies.
A marine aquarium, populated with stunningly patterned reef fish and invertebrates in crystal-clear water, makes a stunning centerpiece for any room.
