Distribution

This species appears to be rare in nature with the type series, which consisted of just a single adult pair, originating from the Uling brook within the upper …

Members of this genus are near-exclusive inhabitants of short coastal streams on tropical, often volcanic, islands, with typical habitats lying above waterfalls or cataracts. This makes them inaccessible to the majority of fishes although other gobies from the genus Stiphodon often occur syntopically, while amphidromous Macrobrachium spp. shrimp and neritid snails are the commonest invertebrates to be found.

Substrates are normally of bedrock with scattered jumbles of rocks and boulders, and while riparian/stream-side vegetation and submerged leaf litter are common aquatic plants aren't usually present. The most favourable habitats all contain very clear, well-oxygenated water which, allied with the tropical sun, facilitates the development of a rich biofilm carpeting submerged surfaces.

Sicyopus spp. are such successful colonisers of these niche environments due to aspects of their morphology which allow them to utilise available food sources as well as employing a remarkable breeding strategy in which some species are known to climb waterfalls (see 'Reproduction').

S. cebuensis is apparently found only in pristine headwater streams and co-occurs alongside the congener Sicyopus zosterophorus plus Lentipes armatus, Sicyopterus lagocephalus, and Stiphodon surrufus.

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 pageFor example, the Behaviour and compatibility section already says this.

Aquarium size

An aquarium with base dimensions of 60 ∗ 30 cm or equivalent should be large enough for a pair or small group but use something bigger if you want to keep mult…

Maintenance

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 s…

Water conditions

Temperature: 22 – 28 °C; increased surface agitation is required to maintain dissolved oxygen levels towards the upper end of this range. pH: 6.5 – 7.5 Hardnes…

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…

Notes

This species is not in the aquarium trade though is maintained by a few private collectors. It can be distinguished from all other members of the genus by the …
