Algae-eating shrimp -- powerful little critters even at one-inch.
Origins: With a name
like Caradina japonica, you have
to suspect the algae-eating shrimps originally came from Japan.
Different species came from
different swamps. All these
similar species like to eat algae.

Algae-eating shrimp are also known as Amano shrimps.
Appeal: Plant-growing
expert Amano-san popularized these hard working crustaceans in his series
of incredibly beautiful books of natural aquaria.
He extolled their well developed algae-eating talents.
So effective were his mentions of the algae-eating shrimps that
many people call them Amano shrimps. He
recommended two per gallon.

Not all algae-eating shrimps look alike.

Cute little beady eyed critters.

Out of algae? They also eat green beans and fish food.

Algae-eating shrimp also eagerly eat a deceased tetra.
Foods: Obviously
algae-eating shrimps eat algae. They
also eat fish food (first). Don’t
feed them anything if you want them to get rid of your algae.
When they run out of algae, they will eat your plants.
Add food at this point. They
also munch on deceased fish. We’ve
never seen them attack fish but would not put it past them.
They do not like the blackish, furry algae.

Housing: If you need an
algae eater for a small tank (or tank with small fish), put algae-eating
shrimps on your payroll. Keep
yours covered. We’ve watched
them crawl out. They are not
helpless out of the water. They
run like a cockroach.

Algae-eating shrimp do not hesitate to exit the water when they feel like
it.
Out of the Water: Most
shrimps go limp when caught in a net – not the algae-eating shrimps.
They instantly crawl out of your net and drop to the floor.
They can jump straight up about four inches.
They flip laterally as much as a foot per flip.
Tank Mates: Algae-eating
shrimps get along great with smaller fishes -- tetras, moons, corys, dwarf
cichlids and others until the “others” grow large enough to scavenge
your scavenging shrimp. Gouramis
with their smaller mouths get along well also.
We’ve never mixed these guys with ghost shrimps.
They’re tough enough to turn them into real ghosts.
Temperature: Your
average tank temperature works fine.

You often find your algae-eating shrimps crawling on your sponge filter.
Temperament: Some people
say algae-eating shrimps are shy. Others
say they are nocturnal. We’ll
just say they’re small and not stupid.
If you provide a forest of hiding places, they will use them.
In sparse tanks, they’re out front.
They love to crawl on sponge filters.
They like sorting thru the detritus they collect.

They blend in like the Predator in the Schwartzenegger movie of the same name.
Décor and Plants: Algae-eating
shrimp love java moss. They
munch on it continuously. Otherwise,
decorate to your taste, not to their taste.

Algae-eating shrimp are huge compared to cherry
red shrimp.
Water: Unless you plan
to breed them, don’t obsess over their water.
Since they come from swamps, you know what you provide will usually
be better.

Captured algae-eating shrimp relax for a moment, then take off for Tokyo.

Here's the first one we've seen with eggs. They're black.

Breeding: We don’t
know how to breed the little rascals, but the Chinese have it figured out.
Our last price list included 300-packs of three different species
of algae-eating shrimp from Taiwan. Apparently brackish water
affects the equation. Protecting
the tasty babies from the adults also ranks high.
Try making a breeding cage out of nylon netting. The babies
should escape thru the mesh.

Stubborn algae-eating shrimp do not necessarily pour out of a catching
cup.
Last Word: When teamed
with otocinclus, algae-eating shrimp complete your algae-eating team.
