My sister is desperate to get crabs and is saving up money to buy a tank just for crabs. However, she's now saying that she wants to kill her fish because I don't want to maintain a brackish setup.
So, are there any freshwater (not brackish) crabs suitable for a fairly small species-only setup?
Any insight is appreciated.

Okay, I'd be prepared to do a brackish setup depending on how easy they are to keep.

1). What type of salt would one use? I have just got some API aquarium salt for my harlequin tank to battle whatever is in there and if I come across any other diseases.
2). How much salt do you add per gallon of water?

You need the salt that they sell for salt water aquariums. Which is not the same as aquarium salt.

Um... pardon me, but if she wants to kill her animals because she can't have what she wants, then she shouldn't have animals. I understand if she's a small child, because they say things like that, but if she's a teenager she needs to be maintaining her own tanks and doing her own research.

She's calmed down now lol!
Betsy, she's 10 and wouldn't really kill her fish, just says things when she's angry: all bark no bite.
She does look after her tank well (under guidance) and does the water changes when her friend comes round for flute practice.

If I need the salt for marine aquariums then I won't bother starting up a brackish (wasn't going to start one unless I knew) so thank you for telling me that.
I might be able to convince her to forget the idea now she's calmed down and has had some food lol!

So now just to settle my own curiosity... Are all crabs available for pets brackish or is there actually a freshwater one? My googling has only come up with brackish crabs.

Haha darn lol
Do you think any actually exist??
I think she's decided it isn't such a great idea now lol (probably because I said she'd have to pay lots of money and she knows she doesn't have it)

Who knows - maybe they are like Santa Clause. Smiley

Has she thought about hermit crabs instead? You have to sterilize the sand and get natural shells - they're terrestrial, but still very cool.

There is a lake malawi crab.Dont come up for sale too often and not cheap.Very pretty though.

Hermit crab might be better for a kid on a budget.

I'll look into a hermit crab if, once set up, they're not too difficult to look after. I've got to keep on remembering that I shouldn't be at home next year so I'll have to entrust the fishes into Liz's (sister) care..

I have never kept them, but there are some members here that have. Kids think they are cool because they outgrow the shells they are in and transfer themselves to new ones - they don't make their own. People in the pet industry try painting shells to make them look more "cool", and the hermit crabs absolutely hate them and go for the non-painted ones first. There have been rumors of some pet stores cracking natural occupied shells and only offering painted ones to force the crabs into them and make them look cooler. I do believe they require crickets or other small insects to eat, but I could be mistaken - at this point, you'd get better info from ye olde google than you would from me when it comes to hermit crabs.

You can get freshwater hermit crabs??!!  I never knew that.  My dad had a hermit crab when he used to have his marine tank set up.  It had the biggest personality of anything else in there.  When dad opened the lid of the tank it used to come scuttling at full tilt across the tank because it knew it was feeding time and it had to position itself to catch any bits of food the fish missed.  I don't remember it getting fed anything special, it just scavenged what fell to the bottom of the tank.

I found a site that made it look really complicated. I could understand the dry sand and a bowl of sorts of water but giving the crab a weekly wash and misting it every day as well as mentioning heat rocks (as you would do for a lizard) made me think it may be more time and money than I had originally thought. I'll keep on googling though.
Any idea on what size tank? They are pretty pricey around here so we couldn't go big at all if we decided to try hermits.

Clare, I think there are land-dwelling hermits as well

I honestly don't know - but you could go plastic instead of glass, if that's cheaper. Smiley

Plastic is definitely cheaper.
Lol I decided once I get my veterinary degree I'm going to move somewhere where I can get cheaper fish supplies (and a job)

Once, when seining a freshwater stream, me and my buds got loads of shrimp, some fish, and a good nuber of crabs, musta been what 10 maybe 12. They were small little things, maybe an inch across. We ate them.


So, yes, I suppose there must be freshwater crabs. But finding them, unless you have access to wild waters, will be next to impossible.

There's hundreds of species of true FW crabs globally...some making it into the pet trade sporadically. The FW Geosesarma sp. sold as "vampire crabs" seem to do well in aquaria.

I **think** the reason you see brackish/estuary crabs being constantly sold is because they live in colonies and are easy to collect in numbers. Here in Jamaica Bay I can fill a bucket up with fiddlers in a 1/2 hour. They literally move in herds during low tide.

For a 10 yr old...two thumbs up on terrestrial hermits.

Ruthy, I think that she would enjoy having a hermit crab. I had some when my kids was little and we would take them out and let them crawl around and such as that. As long as you're gentle with them you can play with them a little.

They are not hard to take care of but it has been so long since we had them that I can't remember what all you need.

A 10 gallon tank, wet sponge, bowl of water, bottle of water for misting them, extra shells and food. I can't promise that I'm 100% correct without doing some reading on them but I think that's about all they need.

I just remember that my kids and I had fun with them.

**Don't buy any with painted shells.
