Also please look at this hat I got. Obsessed. I'm actually writing up an action statement on these guys (Southern Purple-Spotted Gudgeon) for an assessment atm so this came at the perfect time.

Also called “squeakers”, the fishes of Eleotridae family appear to be an important component of the Benin coastal water fisheries, but also have a potential for aquaculture. The current ichtyological survey documents eleotrid fish composition and community structure in the degrading coastal waters of Benin in order to contribute to habitat protection, species conservation and aquaculture valorization. Eleotrid samplings were made monthly from April 2017 to September 2018 in Lake Nokoué, Porto-Novo Lagoon, Coastal Lagoon and Lake Ahémé using castnets, seines, gillnets and traps. Five (5) species, Dormitator lebretonis, Eleotris vittata, Eleotris daganensis, Eleotris senegalensis and Bostrychus africanus have been inventoried. Dormitator lebretonis was the dominant eleotrid making 57.91% – 87.39% of the squeaker assemblages. The highest Shannon-Weaver index of eleotrid diversity (H’=3.82) was recorded in Porto-Novo Lagoon, a relatively less degraded ecosystem, whereas the lowest H’=1.54 was recorded in Lake Ahémé, a highly degraded coastal water. Eleotrids exhibited a relatively high tolerance to environmental quality due to their euryhaline behaviour and the presence of adaptive air breathing organs. A sustainable exploitation of squeakers requires a holistic approach of coastal waters management.

#2913 - Gobiomorphus australis - Striped Gudgeon

Another Sleeper Goby endemic to Eastern Australia. Found in wide variety of habitats from muddy stillwaters to clear streams with rapid currents. Juveniles are common in estuaries near rocks, submerged logs and among vegetation.

Good climbers, able to clamber over wet rocky surfaces such as rapids, waterfalls, or artificial weirs. As with the Empire Gudgeon, males stand gaurd over the eggs until they hatch.

#2912 - Hypseleotris compressa - Empire Gudgeon

A friend of mine back in Sydney has been investigating what native fish live in the stormwater drains around the inner suburbs - one of those species is the Empire Gudgeon, which is an impressive name for a very ordinary-looking fish. That's because it's a bit stressed from being put in the tank. A day later he's back to this -

Unrelated to the Eurasian freshwater cyprinid Gobio gobio, which despite the binomial isn't a goby but is a gudgeon.

Hypseleotris compressa is one of the Sleeper Gobies of the family Eleotridae, a family most diverse in the Indo-Pacific tropics. They range in size from the bigmouth sleeper (Gobiomorus dormitor) of freshwater habitats in the West Atlantic, which is up to 90 cm long, to the Amazonian Leptophilypnion which are under a centimeter. Some Sleeper Gobies are important predators on islands like New Zealand and Hawaii, that lack the predatory fish families of nearby continents.

The bright colours are donned in breeding season - the male will stand gaurd over the 3000-odd eggs glued to plants, substrate, or various garbage, and the fry develop down in the estuary. Surprisingly tolerant of pollution and salinity.
