Care
Redspotted Gobies are relatively easy to care for, which makes them suitable for both beginner and advanced hobbyists. They thrive in well-established aquariums with plenty of live rock and hiding spaces. These gobies are peaceful and can coexist with a variety of tank mates. They are carnivorous, feeding on small crustaceans and zooplankton, so a diet of live or frozen foods such as brine shrimp and mysis shrimp is ideal.
Reproduction
In the wild, Redspotted Gobies form monogamous pairs and are known to spawn within the crevices of rocks or coral. In captivity, breeding can occur if a stable pair is established. The male typically guards the eggs until they hatch, which can provide an interesting spectacle for the aquarist.
Symbiosis
While not known for a specific symbiotic relationship like the clownfish-anemone partnership, Redspotted Gobies do play a role in the reef ecosystem by consuming parasites and dead skin from larger fish, a behavior that can be beneficial in a community aquarium setting.
Habitat
Elacatinus puncticulatus is native to the Eastern Pacific, from the Gulf of California to Panama. They are typically found in shallow reefs and rocky areas where they can dart in and out of crevices for protection. In the aquarium, replicating this environment with ample rockwork can help these gobies feel at home.
