RED LEGGED HERMIT CRABS
Clibanarius digueti
Congregos Ermitanos
Arthropa
super family - - Coenobitoidea (Hermit Crabs)
family -- Diogenidae
genus -- Clibanarius
species - - digueti
Lower Gulf of Mexico and outer Baja to Bahia de Magalena.
Species is usually red in appearance with expanded chromatophores forming blue spots over their cheliped (claws) and walking legs. The antennae and antennules are bright red. The tips of all legs are also red or orange.
This small crab is the best algae eating hermit crab we have tested. Chibanarius digueti feeds on algae that grows on the rocky substrate and mangrove roots.
C. digueti occupies a large variety of shells. This hermit crab is found in the oldest coraline incrusted shells. I have found entire colonies in broken sand worn shells. The crabs from La paz often occupied such a strange assortment of shells that I could identify the colonies before I looked at the crabs.
Both the Blue leg hermits and the red San Sabastion crabs always are collected in clean fresh shells. Both of these crabs have eaten snails in my reef tanks. I have kept C. digurti in reef tanks in colonies of over 10 crabs per gallon with many types of snails.
These red legged crabs are very effective at eating hair algae. I have observed many small C. digueti settle in the center of patches of hair algae and stay there for several days until they have cleared a patch over one inch in diameter. This small hermit crab will clean red sponges and small polyp colonies and not damage them in any way. I have watched these crabs clean red cyanabacteria from new woods polyps and not damage the cuttings.
In nature C. digueti feeds by scavenging the algae that has started to decay from being exposed at low tide. I often find large groups of these hermit crabs on algae covered rocks.
A very important item are the Mexican Red Leg Hermit Crabs. These little suckers are amazing! I had several rocks which had Cyanobacteria red slime algae covering them from the old system.
The morning after adding the crabs I witnessed "Herds" of about 6 or 7 crabs each that would concentrate on a rock at a time, totally eliminating the Cyanobacteria I have never heard of a cyanobacteria eating critter like this and it seems they actually prefer it! A week later, my tank was almost completely free of red slime.
I have not seen them harm anything in the tank. I even tested this in another tank. I placed a small rock fully covered in Cyanobacteria and 8 crabs in a 10 gallon tank for 4 hours. In 4 hours, the rock was about 50% clean!*

One inch long pointed shell, it can get in between rocks, it is a great glass cleaner. This snail cleans in zig zag pattern. It's radula is able to remove diatoms so well that they do not regrow from the original algal film. This snail does not dislodge or disturb any specimens.

LIVE SAND ACTIVATOR
GARF GRUNGE*
GARF GRUNGE* HAS A VERY LARGE NUMBER OF CORALINE ALGAE SPECIES IN IT.
NO WILD LIVE SAND CAN HAVE THE BIODIVERSITY FOUND IN THIS ACTIVATOR!
$5.00 PER POUNDReef aquariums require a large variety of organisms to filter the water properly. Aquarium habitat is very different from ocean habitat.
Live Sand from a natural reef is good for starting marine aquariums, but each location on a reef has a limited number of species. Poor packing and shipping methods further deplete this fragile wild population.
We have been keeping an unbroken chain of successful reef aquariums in Idaho since 1977. Several times during this period we have had over 100 aquariums. We have researched captive breeding of such diverse species as Chambered Nautilus and Acropora coral.
LIVE ROCK RESEARCH
Our continuing research into the commercial production of tank raised live rock has allowed us to purchase tons of prime live rock and live sand. We select species from the rock for our live rock genetic bank.During the last year I was able to purchase over 1000 lbs. of the live sand and rubble from the bottom of the live rock holding tanks at several of the most famous live rockers.
This mixture was much more than just live sand!! Hundreds of invertebrates from the tons of live rock held in these tanks are now reproducing here in Idaho.
RESEARCH COLLECTING TRIPS
This mixture is now being added to by myself and Sally Jo. We are collecting sand stirrers and filter organisms on our research trips. We have made several trips to Mexico during the last two years looking for a site for a live rock farm. We are able to select various types of live sand for our experiments.Last year Tom Frakes and I Explored Coronado Island in the Sea of Cortez. We found a bay with sand made up of branching coraline algae fragments. This coraline is the fastest growing dark purple and blue types I have found.

�the most important part. This is a "Grunge" from G.A.R.F. What the stuff contains is a culture of sand, coral rubble, small reef rocks, macro-algae, annelid worms, small pieces of sponges and corals, snails and crabs that is some of the coolest stuff I have ever seen!
I still keep seeing different things I didn't see before. We got 10 pounds about a week after the system was set up and mixed it in with the top layer of sand. This really gave the reef a pleasing natural look since it is very coarse and has a lot of color to it� *
