Not sure what’s happing with my red claw crab and I’m freaking out.!!!

[Rocky998]

So I actually exchanged a big mean one for this new smaller one. I had 3 the whole time the spot on her back was changing colours. One was suffering because the big one chopped her 2 legs and her claw, she was okay, she was doing well she was climbing up the filter and holding herself up there, she was going good until he got her other leg, but any dip or movement from the filter water would flip her over and then she was stuck and couldn’t get herself back over.

Name her after a pirate ☠

But yah, glad you got that one outta there.
I still don't agree with you getting another one though. Because you may give yourself more problems

I can't tell from the pictures. This isn't the Vampire Crab is it ? They are not aquatic.

Not completely aquatic anyway. But they do go into the water

Read the article on Geosesarma dennerle and Geosesarma hagen in the May / June 2022 Tropical Fish Hobbyist magazine. They are known as , either , Red Devil crabs or Vampire crabs in the trade . They are a terrestrial crab suited properly to a terrarium , if the creature in question in this post is that particular one. All I know is what I read.

I could have sworn they go into water. Shallow water but still water.

Google tells me that red claw crabs are Perisesarma bidens and that they need a tank with 3 parts water and 1 part land. But that's just google, you need a crab expert who can identify which species you actually have, and how they should be kept.

Yes, you are right about that but if the OP's crabs are Geosesarmarma species they aren't fully submerged all the time animals.

Yes that is absolutely true

Let's see what your new test kit reveals about your water params

That Top Fin conditioner isn't the best, when you run out, get some Seachem Prime, or API Tap Water Conditioner

You don't need the carbon, the "cleaner", or the salt...the more chemicals you add to a tank, the more you complicate matters

I do need the salt, as red claw crabs live in brackish water.

Why haven't you been adding salt if you know they need brackish water?

When did I say I never added salt.??? In the very beginning I posted of picture of absolutely everything that went into my tank. There’s salt in that picture….

Oh in that post you made it sound like you didn't have any and you needed to get some sorry... I completely forgot about that other post...

BUUUT, I don't think that kind of salt is the stuff you need for a brackish tank. But I don't know much about brackish/salt water so someone may correct me. As far as I know you would need a different type of salt... (Again, could definitely be wrong)

i have Perisesarma bidens, they are red claw crabs. They need water and land, not necessarily land but access to air, they have a big bridge they climb on. They live in brackish water, because they don’t survive as long in fresh water. See here’s the thing.

Nothing has been changed, nothing new added, nothing new done, I’ve had her for 8 months.
So unless someone truly knows why she is changing colours, I’m just gonna stick with ammonia poising until I can get it tested

It’s the exact stuff I need

They are red claw crabs. Perisesarma bidens
