Any Freshwater crabs from Amazon?

[Captain tank]

Hey, does anyone know if some site sells freshwater crabs from the Amazon river basin? I've watched some documentaries lately and saw that there are freshwater crabs in the rivers down there. And I've wondered if they sold any for the aquarium trade? I've got an Amazon bio type fish tank, so the crab would have to be able to go with these fish listed below.

Did you happen to find out what kind of crabs they were? Many tropical crabs are fairly terrestrial. At least that has been my observation, given the opportunity they will spend most of their time out of water. However to answer your question. If they are provided with ample of cover and are not small enough they will probably be fine. Without cover, fish harass crabs and crays.

The ones I saw in the documentary were redish and looked like Sally light foot crabs... But I know they were fresh water because the documentary was only in the Amazon region. And I didn't know any names, the narrator never talked about them, it was just a small scene that showed them in the background. They did talk about a fresh water sponge though which was really cool. Never said what kind of sponge it was.

There are several species of freshwater crabs, but I don't know of any that are fully aquatic. I caught this guy while fishing at my local pond in San Jose, however these mountain crabs seem to come out of the water fairly readily. That said, I've never tried to keep one solely in water, it might work.

About fresh water sponges, there are actually quite a few of those. I believe the most interesting reside in Lake Baikal. However, it would surprise me if your region of America doesn't have a few. Unfortunately most are fairly drab looking clumps of green or brown, nothing like the tropical sponges most people are familiar with. i will see what I can dig up.

The Amazon basin water is generally soft and acidic, and is not known to support diversity of shell fish because there is lack of calcium and magnesium to build shell. Lake Baikal and African Rift lakes are the opposite that support high density and diversity of shell fish.

There's a wonderful diversity of Neotropical freshwater crustacean life that is hardly if ever seen in the aquarium trade.

Collection records of two families of freshwater crabs (from this interesting survey article):

Brazil has 6 pseudothelphusid and 10 trichodactylid genera, with 19 and 31 described species respectively and certainly more yet to be described.

In the US, now and then you might see one or two species of Amazonian Dilocarcinus (a trichodactylid) come in ... good luck getting ahold of any of the rest.

This Brazilian webpage has photos and profiles of some of these many species (the Aegla however are not true crabs at all but anomurans, distant relatives of hermit "crabs").

That's

cool, thanks Veneer... I'll have to read up on it. That sounds cool, never heard of Aegla before.

Do you know of any online sites that legally sell some of these crabs for the aquatic hobby? Cause I'd really like to house one in my tank... Maybe even breed them if I'm really lucky with them.

I don't know, would like some myself. They may be showing up on exporter lists but not getting brought in due to insufficient interest. Best bet's probably talking to someone open to oddball requests like Wes.
