These gobies aren’t too difficult to keep provided some basic requirements are met. Most importantly the water must be clean and well-oxygenated at all times so we suggest the use of either an over-sized filter, additional powerheads, flow pumps, or airstones. While torrential conditions are unnecessary a turnover of 10-15 times tank volume per hour is recommended, though with good oxygenation a lower rate of 5-10 times per hour is feasible.
Base substrate can either be of gravel, sand or a mixture of both to which should be added a layer of water-worn rocks and pebbles of varying sizes, of which some should ideally be raised with flattended upper surfaces. Aged driftwood can also be used but avoid new pieces since these usually leach tannins which discolour the water and reduce the effectiveness of artificial lighting, and these gobies naturally dwell in very clear water.
If keeping multiple males of one or more species structure the rockwork to form plenty of potential hiding places and broken lines-of-sight to reduce the likelihood of excessive aggression. Although not a feature of this species‘ natural habitat aquatic plants can be used with hardier genera such as Microsorum, Crinum, and Anubias likely to fare best
Since they require stable water conditions these fishes should never be added to immature set-ups and a tightly-fitting cover is necessary since they’re able to climb glass and are prodigious jumpers. Weekly water changes of 30-50% tank volume should also be considered mandatory.
