fiddler crabs and brackish water?

Question

I have had my fiddler crab for maybe six months. the pet store told me keeping him in straight tapwater would be fine. but i have been researching fiddler crabs lately, and it says that fiddler crabs not kept in brackish water will die within a few weeks. it has been over six months, and he is still alive and well. should i transition him to brackish? or would the change harm him? what should i do?

Answer 1

Fiddler crabs can adapt to freshwater, but they won't live as well as they would in brackish. It's kind of like molly fish - they are sold as freshwater fish, but they can manage half decently in freshwater. They won't thrive or live as long, but they can survive surprisingly long time.
You should transition him to brackish. Do it slowly, of course, and it can only make things better for him.

Answer 2

You will want to transition your crab over to brackish. Make sure you do it slowly over a period of 4 weeks, because the beneficial bacteria in brackishwater is different than freshwater. Get a good hydrometer and marine salt(NOT aquarium salt) and increase your SG by .001 every week. Good luck!

Answer 3

a million) Yeah. you're wonderful see you later as there are no fish in there with rather long fins. 2) that i'm uncertain approximately. i've got consistently used aquarium salt... 3) Mine merely bypass in my conventional fish tank so... 4) they are able to consume tropical nutrients, yet I feed mine crab and lobster nutrients, which you will locate at Petsmart. 5) They like to conceal out in places, so merely something which will sink and that they are able to conceal in. each so often they even climb up the clear out and what no longer. 6) this is a count of netting them and putting them in say a tupperware to flow them. Mine have never even come close to to pinching me. i haven't even had to the touch them. it could merely be somewhat dramatic each so often. they are escape DEMONS. 7) i could probably placed like 3 at maximum... 8) Crab nutrients... Feed them like 4 or 5 pellets each 2 days. they are notably easy. 9) uncertain... they could harm them nonetheless. 10) No theory. 11) Any conventional fish tank clear out. do merely no longer be stunned in the event that they climb it!
