Distribution

Described from the island of Halmahera in the Maluku Islands (also referred to as the Moluccan or Spice Islands) archipelago, Indonesia. It may have a wider ra…

Habitat

Members of this genus are near-exclusive inhabitants of short coastal streams on tropical, often volcanic, islands, with typical habitats lying above waterfall…

Aquarium size

An aquarium with base dimensions of 60 ∗ 30 cm24 ∗ 12 in or equivalent is large enough for a pair or small group but use something bigger if you want to keep m…

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. 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.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the profileFor example, the Behaviour and compatibility section already says this.

Water conditions

Temperature: 22 – 28 °C72 – 82 °F; increased surface agitation is required to maintain dissolved oxygen levels towards the upper end of this range. pH: 6.5 – 7…

Diet

Appears to be a specialised predator since it does not graze biofilm in the aquarium but willingly accepts small live or frozen foods such as bloodworm, Artemi…

Behaviour and compatibility

Can be kept in a community provided tankmates are chosen with care. Peaceful, pelagic species which naturally inhabit well-oxygenated streams such as Tanichthy…

Sexual dimorphism

Adult males possess relatively long unpaired fins and the first dorsal-fin is noticeably extended compared with the second, whereas in females the unpaired fin…

Reproduction

Observations of courtship behaviour and the occasional spawning exist but to date no-one has managed to raise fry of any Sicyopus species in aquaria. This is u…
