Pretty good-looking patriot crab, even if he is left-handed.
Origin: Last millennium, we never really knew where patriot
crabs came from until one of our Nigerian customers saw them and said
they were very common in Nigeria.

Soap Dish Crabs: Patriot crabs were originally shipped in
plastic soap dish containers and were thus called "soap
dish crabs." They came in yellow, purple, red, and blue.
They have a long list of AKAs, so you'll find them under a variety of
names, like rainbow crabs, moon crabs, Columbian crabs, and
others.
LA
One submerged. One emersed.
Life Style: Adult patriot crabs like to mix it up.
However, most are just as happy to hide. In the wild they would
dig burrows. In captivity they're just as likely to scoot under a
rock or piece of driftwood. They live at the edge of the water.
They survive under water for long periods but need access to land to
catch their breath. Like all crabs, they have gills that must be
kept moist, so they need access to water at all times. A tank with
half water and half land works well. Or you can give them an easy
to enter and exit dish of water and mostly land. There's no magic
formula.
LA
Right-handed crab and left-handed crab.
Water: Do they do best on freshwater or brackish water?
Yes. They do just fine on both.
LA
Typical crab hang out. A little on the tacky side. You can
see two of the four in here.
LA
They're all out of sight here.
LA
Patriot crabs do fine in bare tanks.
LA
And they show up well over white gravel.
Substrate: Bare tank, sand, gravel (natural or colored) make
little diff to your crab. However, they seem to blend into natural
and multi-colored gravels.
Live Plants? Patriot crabs are scavengers. They eat
whatever they find -- including live plants.
LA

Temperature? Patriot crabs do well at 75 to 85 F. In
the wild, they probably face much more variation in their ambient temp.
Your best bet is to call a friend in Lagos and ask for their temp each
day. Suffice it to say, they probably cool off a great deal at
night.
LA
Four confused patriot crabs not knowing who to argue with first.
Threats. Patriot crabs are not schoolers like many of the
mini-crabs. They fight. Give them plenty of room.
Copper is also a killer of all invertebrates. Avoid medications.
And keep all long-legged shore birds out of their habitat.
LA
Older crabs lose some of their bright colors. He also lost one of
his legs. Incredibly careless.
LA
Oops. Here it is. He'll grow it back on his next molt.
Dis-Armaments. When patriot crabs argue, they try to tear off
each other's arms and legs. If they lose any parts, they are at a
disadvantage when eating and when fighting. Separate any walking
(or non-walking) wounded. They will grow new parts at their next
molt. It may take half a year for them to get back into fighting
trim.

Shell Shedding. Crustaceans grow by taking in water, flexing
their muscles, and splitting their shells. They then wriggle
out of their former old shells and scuttle under a rock until their new
shells harden. At this stage, they are softer, helpless, and
tastier. Their fellow crabs have few compunctions against
cannibalism at this time. They will usually eat their old shell so
the calcium does not go to waste.
LA
Belly of a male patriot crab.
LA
Ditto female patriot crab.
Sexing. Look at their tail flap. It's narrow on the
males and wider on the females. Pretty much like all crabs.
Don't worry, you won't breed them anyway.
LA
They scuttle right out of a net.
Capturing Crabs. You can learn a great deal by picking up a
patriot crab -- especially if you try it bare handed. If you use a
net, they scuttle out of that pretty fast. A plastic drinking
glass (don't worry about plastic glass being an oxymoron) probably works
best.
Mixing with Fish? We've already mentioned that 100% water
works not so well. That doesn't mean no one does it. If you
hold a patriot crab in your hand, you will see why fish do not do well
in the same habitat.
LA
His mouth is at the top of his chest.
How Do They Eat? You'll notice patriot crabs stuffing food
into the top of their chest. If you saw the movie predator, you
have a good idea of how their mouth works.
LA
They quickly learn to eat from your fingers. Watch yours.
LA
They do like dead (and live) fish.
Last
Words. Patriot crabs do like dead goldfish or whatever else
they find. They'll do just fine on any of the pelleted pet foods
for birds, lizards, ferrets, cats, dogs or whatever. If you like
to add supplements, add a piece of cuttlebone. Patriot crabs are
as easy to keep as a crawdad. LA

In shallow water with eyes popping out of the water.

Never to late for a snack.

You can see his mouth here.

Totally submerged and over sand.
LA
Totally emersed and looking for trouble.
LA
Always happy under a rock.
LA
Sometimes fish can be a little too snoopy.
