Freshwater aquarium crabs can be kept by themselves or within a community tank with other fish
Classroom Tank >Hi crew! >>Good morning, Joy, Marinahere. >One of my students took home the class pet for summervacation, renamed her, and now my red eared slider has a new home and Ihave a 55 gallon tank to fill. Help!! I'vepurchased an aquarium divider. I want to know can I have acrayfish or lobster on one side of the divider and a shrimp and sometype of aquatic or semi-aquatic frog on the other. >>Yes, you can do this. >Possibly a fish or two if you canrecommend ones that won't be eaten. >>Not with thecrawdad/freshwater lobster, but if you have something like a smallleopard frog on the other side, then you can put in mosquito fish orsimilar small fish. Also, consider land hermit crabs (theCaribbean variety). I don't think they can pinch anyworse than a crawfish! They do require a different setup,though. If interested, check out for bestinformation. >My concerns are having species that have the sametemperature and water hardness requirement. >>Not exactly a worrywith frogs and crawdads, very hardy, as are most commonly availabletropical fish. >Some of my students have vision issues, so could youplease recommend colorful species (our school uniform colors are whiteand blue, I would love to say my aquarium creatures are dressed inuniform). >>Sorry, but most colorful species are VERY specializedand difficult to care for, and the ones that I can think of that wouldmatch your school colors are poison dart frogs. Even thoughtheir stay in captivity and lack of variety in diet seems to seriouslyreduce toxin levels, still not a good idea in my opinion (mostly formeeting their requirements). There does exist, however, aBLUE freshwater crawfish that is also known as a freshwaterlobster. This may take some searching tofind. Marina
Also, do not buy what is sold as “Freshwater Aquarium Salt”. While the salt is safe for use with hermit crabs, it contains only a few elements rather than a full mix that is helpful to hermit crabs. The two major brands that are NOT the right kind of salt to buy are API and Doc Wellfish. These types of salt are not going to be helpful in the long run, but they are not harmful.
Crabs are scavengers of any type of edible matter they find

When it comes to invertebrates, many aquarists immediately think of shrimp or crayfish. However, there’s another group of fascinating inverts that can be kept in aquariums: crabs! Unfortunately there is still a lot of misinformation out there about these clawed critters. Many brackish crab species are sold as suitable for freshwater tanks and many species that require a land area are marketed as “fully aquatic”, which inevitably leads to dead crabs and disappointed aquarists.Although not the easiest freshwater crab species to keep in the aquarium, panther crabs originating from Sulawesi can make an interesting project for more experienced aquarists. With a carapace size of up to 8 cm (3.1 inches) they are one of the larger crab species on this list, which means they require a relatively large aquarium (at least 20 gallons/76L for one crab). Tank size is especially important when housing multiple crabs together, as they are quite aggressive both towards their own species and other tankmates. Keeping pairs or harems is usually the way to go: multiple males don’t seem to go too well together.Red-clawed crabs (Perisesarma bidens, formerly Sesarma bidens) are often sold as "freshwater" crabs, but really do their best in brackish water. They are widespread in Asia, where they dwell in costal mangrove swamps. They can survive in full saltwater and freshwater, but do their best in a brackish aquarium.Live freshwater aquarium crabs shipped safely to your door!
