Golden Malili Goby (Mugilogobius rexi)

Golden Malili Gobies are good-looking, peaceful, and hardy fish that are best kept as a male and female pair. If you would like more than one pair in the same aquarium, ensure that there are plenty of visual barriers amongst the d├ęcor and that the aquarium is spacious; otherwise, the males might fight. These fish have slender yellow bodies and rounded fins, with the males displaying brighter colouration and patterning compared to females.

You can keep these Gobies in a species-only aquarium or a community aquarium with similarly sized peaceful species that appreciate similar water requirements. Ideal tankmates could include Peaceful Dwarf Barbs, Tetras, Ricefish and Dwarf Rainbowfish. It would be best to avoid much more larger, aggressive species.

It is not unusual to see these gobies hovering in a diagonal position above the substrate.

Golden Malili Gobies require a well established, well-filtered aquarium with efficient filtration; however, water movement should not be too strong. The substrate should be either a soft sandy substrate or fine smooth gravel. In addition, these Gobies will also need many resting places that you can achieve with driftwood as well as caves formed from slate and rocks. These fish will also appreciate small pebbles. Finally, having a few areas of dense planting will help provide cover, which these fish will also enjoy.

It is recommended that you also perform frequent water changes as this will help keep the nitrate in your aquarium to a minimum.

Natural Habitat

In Southeast Asia, Golden Malili Gobies are endemic to Lake Towuti and Lake Mahalona in Sulawesi in Indonesia. These Gobies inhabit moderately flowing, shallow warm waters with a silty substrate, and their habitats contain thick clumps of aquatic plants, including freshwater mangroves.

What to feed the Golden Malili Goby

Golden Malili Gobies are not particularly fussy about food; however, they do prefer meaty foods. Therefore, it would be best to provide your gobies with a varied diet. The diet can include high quality dried foods such as flakes, granules, sinking pellets and algae wafers and supplement them with frequent feedings of live or frozen foods such as daphnia, cyclops, mosquito larvae, and vitamin-enriched brine shrimp.

How to sex the Golden Malili Goby

It is relatively simple to differentiate between male and female Golden Malili Gobies. Mature males are usually a much brighter yellow than females, have larger fins and possess a pattern of dark bands in the fins. In contrast, females are generally a much paler yellow, and their fins are translucent without any patterning.

How to breed the Golden Malili Goby

Golden Malili Gobies have been known to breed in the home aquarium; however, raising the babies can be challenging. Currently, there are no records on the successful upbringing of these Gobies fry.

These Gobies lay eggs in round clutches on decor with vertical surfaces.

If you would still like to attempt to raise these fry, sucking the hatched larvae out of the breeding tank and placing them in a separate tank is advised. The raising tank will need to be no bigger than 12 litres. In addition, you should provide the fry with infusoria or powdered fry food and perform regular small water changes, so waste does not accumulate in the tank and lead to high water pollution.
