Sexing[edit | edit source]

The second dorsal fin is elongated in the male.


Tank compatibility[edit | edit source]

A large semi-aggressive fish. Can be somewhat territorial. Not much of a nipper, but will definitely use it's weight and size to strong-arm other fish. With enough space they can be quite docile, and can be easily bullied by more aggressive fish (such as certain types of cichlids).
They will eat anything that will halfway fit in their mouths (pretty much anything 20-30% of their size), so it is best to house them with similar sized tankmates. They can be quite sluggish, so very fast moving smaller fish like Giant Danios usually don't have problems living with this big fish. The D. maculatus spends most of it's time in the middle to lower water column, so upper column dwellers are usually okay (again, always consider speed and size).
Raising small Jade Gobies with fish it will eventually greatly outgrow can contribute to the success of housing these monsters with smaller fish, but there are no guarantees, and adding new small tankmates with a larger Goby is never a good idea (even if the Goby grew up with small fish). The best bet here is to start a tank with all juveniles and raise them together.
Recommended: Raphael catfish, Synodontis cats, most similar-sized catfish, Pacus, less aggressive species of SA/CA Cichlids, large Gouramis (if your Goby is under 22.9cm (9")), Giant Danios, and other less aggressive fish suitable to a brackish aquarium.


Diet[edit | edit source]

An omnivorous fish that will accept pellet and flake as well as live/frozen food like bloodworm and brine shrimp. Will also accept blanched vegetables and vegetable matter.


Feeding regime[edit | edit source]

Feed once or twice a day.


Environment specifics[edit | edit source]

Although it can reach a considerable length, usually the fish remain smaller. Keep them in a spacious tank with lots of driftwood and a dark substrate, these fish may eat plants so silk plants are best. Well filtered water is necessary. The fish occur in the wild in pure fresh water and in brackish water. Adding a bit of salt to the tank can be beneficial.


Behaviour[edit | edit source]

A potentially aggressive fish.
