Temperament:

These gobies are peaceful and non-aggressive, making them suitable for community aquariums. They are generally shy and prefer to hide among corals or rockwork, so providing plenty of hiding places is essential.

Sexual Dimorphism:

There are no noticeable differences in appearance between male and female Citron Clown Gobies.

Lifespan:

The average lifespan of a Citron Clown Goby in captivity is around 3-5 years. With proper care and a suitable environment, they can live even longer.

Diet:

In the aquarium, Citron Clown Gobies are carnivorous and should be fed a varied diet. They will readily accept small meaty foods such as frozen or live brine shrimp, mysis shrimp, and finely chopped seafood. Offering multiple daily feedings is important to ensure they receive enough nutrition.

Aquascaping Recommendations:

When setting up the aquarium for Citron Clown Gobies, it’s important to provide plenty of hiding places in the form of live rock or coral branches. This will mimic their natural habitat and give them a sense of security. Creating a well-established reef environment with live corals and macroalgae will enhance their overall well-being.

Captive Bred Availability:

The Citron Clown Goby is available as captive-bred specimens, which are generally hardier and more adaptable to aquarium conditions than wild-caught individuals. Captive-bred fish also help reduce the impact on wild populations and support sustainable aquarium practices.

Compatibility with Other Fish, Invertebrates, or Corals:

Citron Clown Gobies are generally peaceful and can be kept with various tankmates. However, it’s important to choose compatible species that won’t outcompete or harass them. Here are five specific tankmates that make good choices:

1. Firefish (Nemateleotris magnifica) – Peaceful and adds vibrant color to the aquarium.
2. Yellow Watchman Goby (Cryptocentrus cinctus) – Similar in size and temperament, they can form a symbiotic relationship with pistol shrimp.
3. Banggai Cardinalfish (Pterapogon kauderni) – Peaceful and visually striking, they make great companions for gobies.
4. Clownfish (Amphiprion species) – Clownfish and gobies often coexist in the wild, and their presence can create a natural and dynamic display.
5. Fire Shrimp (Lysmata debelius) – These shrimp can help groom and clean the goby, forming a mutualistic relationship.

These are just a few examples, and compatibility may vary depending on individual fish and tank conditions. Always monitor the behavior of tankmates and be prepared to make adjustments if necessary.
