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.

Feeding

In the home aquarium, the Golden Malili Goby will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

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.
