Aquarium Set-up: Fish-Only-With-Reef-Rock Aquariums
A fish only with Reef Rock (FOWLR) aquarium is a great way to enjoy some of the most colorful and fascinating marine species. These beautiful but often aggressive fish would create havoc in a confined reef system with invertebrates and live corals, but in a Reef Rock aquarium you can enjoy their unique splendor without worry. Better yet, FOWLR setups are typically less expensive, easier to keep, and less demanding than coral reef aquariums.
Triggerfish are best known for their striking triangular shape and variety of different colors and patterns. They also swim in an unusual fashion, using their dorsal and anal fins. They earn their name from the first dorsal fin, which has a very strong bone that can be locked into place, helping aid these fish in maintaining a position within rockwork.
Pufferfish have the amazing ability to expand their bodies to over twice the normal size when threatened. They are a slower moving fish with a beak-like mouth and two fused front teeth. Their jaws are extremely strong, which helps them feed on their favorite food, crustaceans. These fish are very personable, and will learn in time to feed directly from their owner's hand.
Large Angelfish are very colorful and hardy. They have interesting swimming patterns that can add appeal to your aquarium. Many species of angels will also help control algae as they continually graze upon the rocks.
Tangs, commonly referred to as Surgeonfish or Doctorfish, have small scales and one or more scalpel-like spines on each side of the tail. These spines are used in aggression and for defense. Tangs appreciate hiding places, plenty of room to swim, and a diet of algae and dried seaweed.
Wrasse are best known for their bright colors, elongated body, and pointed snout. Some Wrasse will pick parasites and dead tissue from larger fish, including predators. Most Wrasse bury themselves in the sand at night, and also when threatened.
