Always a Good Time with Garibaldi

Named after the famous Italian revolutionary, the garibaldi (Hypsypops rubicundus), also known as the marine goldfish or the catalina goldfish, is a species of damselfish found throughout the northeastern Pacific Ocean, particularly in kelp forests and rocky reefs along the North American coasts from central California in the US to Baja, Mexico.

H. rubicundus can grow to be over 38 cm (15 in) in length, making them the largest member of the damselfish family. Juveniles are red with blue spots, while adults are a vivid, solid orange. This color is what gives the garibaldi fish its name; the Italian Giuseppe Garibaldi and his followers were known for their red or orange shirts. Because they’re so brightly colored, marine goldfish might seem like easy targets for potential predators. However, garibaldi males are actually highly aggressive and will attack anything that enters their territory. The juvenile markings are similarly bright to advertise that they’re not there to pick a fight with older males.

Though males guard their territory year-round, mating only occurs from March to July. Males construct nests about 30 cm (12 in) across, removing all vegetation except for red algae. They then swim around their nest, displaying their fins and making loud clucking and grinding vocalizations. If a female is impressed, she deposits up to eggs 15,000 eggs in the nest, and the male fertilizes them. He then guards the eggs from almost-- including the mother, who may try to eat them. However, he does make exceptions for other females, especially as they are more likely to chose nests which already contain eggs. About three weeks after being laid, the eggs hatch and the young disperse. It takes them about five or six years to reach maturity, and individuals can live between 10 to 12 years.

The marine goldfish’s size and aggression wards off most predators, but larger animals like sharks, seals, and sea lions will hunt them on occasion. Younger individuals are also often targeted by sea birds like pelicans. Garibaldis themselves consume invertebrates, particularly sponges tubeworms, and nudibranchs, as well as algae. Despite their territoriality, H. rubicundus has also been known to gather in groups higher up in the water column; this may be a time for males to familiarize and for females to scout out potential mates.

#1747 - Parma mccullochi - McCulloch’s Scalyfin

A Pomacentrid native to the SW of Australia. Juveniles are a similar shape (parma is Latin for little shield), but have brilliant blue upper parts and a bright orange belly. 

Around Perth, at least, they’re strictly herbivorous, and quite fussy about which algae they will eat - to the point that the species growing within their territory will be quite different to those growing outside it. As such it’s an ecosystem engineer, maintain patchs of high species diversity in the middle of kelp beds. 

They pair up in breeding season, and the male will stand gaurd over, and aerate the eggs, once they’ve been glued to a surface.

Yellowtail Damselfish (Chrysiptera parasema)

Here is another beautiful Chrysiptera, we call this Yellowtail Damselfish from the Indo-Pacific region. This fish is reef-associated and is a semi-aggressive and easy to keep fish. The Body is blue and just the tail is yellow with two black strips across the mouth to eye. Spotted at a depth range up to 20 m and can grow out to be 2.8 inches. This fish is very popular in the hobby and often times…
