The Ocellaris Clownfish, also known as the False Percula Clownfish, False Clown Anemonefish, and Anemone Demoiselle, is found associating with anemones throughout the Indo-Pacific. It can attain a length of 3.2″ (8 cm) in the wild, but aquarium specimens rarely exceed 2″ (5 cm) unless they are imported large. This fish is sometimes sold as the Percula Clown, even though it is not. The color pattern is very similar, but it is not as bright orange. The advantage of the Ocellaris is that it is much hardier. Tank bred specimens are currently available for purchase.

It is a long-lived clownfish that is excellent for the beginner hobbyist. It does best in the presence of anemones such as Heteractis magnifica or Stichodactyla sp. Like the related damselfish, it is well-suited for all but the most predatory tanks.

Tank bred clownfish are very hardy and durable fish making them a perfect addition for the novice or seasoned aquarist. If introduced to the aquarium at the same time, many varieties of tank bred clowns can be maintained together in the aquarium.

Although there are no external characteristics to differentiate male and female, all clownfish are sexually immature when hatched. Meaning that the fry do not have a pre-determined sex, and develop into males and females depending on the hierarchy of the school. A pair will lay eggs along the base of the host anemone, using it to protect the eggs. The eggs normally appear orange in color. Without proper preparation, rearing in the average aquarium is nearly impossible.

This clownfish is an aggressive eater. It will take most meaty foods and frozen herbivore preparations.

aquariablog’s take: Who doesn’t love the clownfish? Mine is hysterical and totally fearless. He does laps back and forth across the tank and is the only fish I have to watch for when I have my hands in the tank. He goes for me every time..and they DO bite. Also most likely fish to get a dumb name….my wife named ours “wiggles.”

The Yellow Watchman Goby, also known as the Watchman Yellow Prawn, Yellow Shrimp Goby, or Watchman Yellow Goby, was first discovered in 1936 by Herre. The head and body are yellow-orange with bright blue spots on the head and fins.

It requires a 30 gallon or larger aquarium with plenty of loose coral rubble, ample swimming room, and a sand bottom for burrowing. It rarely becomes aggressive towards other fish, but it is territorial, and will fight with its own kind unless they are a mated pair. It may try to jump out of the aquarium or other small openings, therefore, a tight-fitting lid is required to prevent escape.

The Yellow Watchman Goby diet should include a variety of mysid shrimp, brine shrimp, table shrimp, and frozen preparations for carnivores. It should be fed at least twice per day.
