Comments: This species is small, interesting, hardy, and fun to watch.
Origin: fast flowing streams with rocky bottoms in Sri Lanka.
Maximum Size: about 2.5" long and very slim.
Behaviors: swims through out aquarium landing to rest on leaves and driftwood also attaches to the glass.
Compatibility: White Clouds, Danios, and perhaps small Rainbowfish.
Temperature: cooler than most of the fish we offer for sale. 72 to 78-degrees F. with 75 perhaps ideal.
Feeding: as usual feed them premium fish food flakes and the smallest pellets.Seems to prefer small live or frozen foods like bloodworms.

Water Conditions: pH of about 6.5 to 7.5 and of moderate hardness, which is close to most of the water in North America.
So it's probably best not to fiddle with your water, unless it's very high in minerals, then you might add some deionized water to dilute the minerals.
Aquarium Size: a few can live in 20-gallon aquarium. Probably a 20-gallon long aquarium is best.
Decor: they do not need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water.
Click here for more about aquarium gravel. They will also need rocks or driftwood to climb on.
Live plants are beautiful and improve the water quality.
Aquarium Filter: Bio-Wheel Filters are highly recommended.
Most 20-gallon aquariums will do well with one Penguin 200B Filter.
But this fish is from rapidly flowing streams, so a Penguin 350B Filter is probably even better, because it will create more water flow.

The addition of Lava Rocks will keep nitrates in the ideal range. Click here to learn more about using Lava Rocks in aquariums.
Life Span: unknown to us but probably at least a few years and hopefully more.
Gender: easy to distinguish as males are more colorful and when mature have a larger top (dorsal) fine.
Breeding: apparently they have been spawned in aquariums a few times. But the eggs hatch into tiny larvae that naturally would wash into the ocean, making the fry very difficult to raise.

Popularity: this fish is expensive and rarely seen in aquariums, but it should be more popular.
Variations: none known to us, but this species lives in many separated rivers and are said to vary in patterns from river to river.
Names: the scientific name is Sicyopus jonkkaasi. We hope you've enjoyed reading these comments.
