View Full Version : Any way to treat hermit crabs during/after quarantine?

Is there a safe way to preventatively eradicate non-obligate parasites (such as uronema) on hermits, snails, chaeto, etc?

I've had a group of hermits and snails in QT for 9 weeks, so they should be clear of ich and velvet, but what about uronema and other infections that don't require a fish host? Is there anything I can treat the invert QT with to eradicate any leftovers that have survived the 9 wk fallow period? It seems like all the available treatments, CP, copper, formalin, etc, cannot be used with inverts.

I know I might seem overly paranoid, but I suffered (actually, I should say the fish suffered) a 100% loss due to presumed velvet several months ago, and I'm determined to never experience that again. The culprit was either a ball of chaeto or a conch, who is still happily motoring around the sand bed, hence my concern.

Thanks in advance.

I don't think there is a such thing. I just do extended quarantine and press my luck.

72-90 days is the time needed, not 9 weeks. 9 weeks is only 63 days.

I was using the 9 week figure in reference to ich-related fallow period seen in this thread (http://www.reefcentral.com/forums/showthread.php?t=2041951). I believe 11 weeks is necessary to be 99.9% certain that all stages would be gone, but the 3 standard deviations gets you to 99.7% at 9wks, which is close enough for me, at least.

My concern is the possibility that something non-host-dependant, like uronema, could hitch a ride and simply wait out the fallow period, since it does not require a host.

Am I being paranoid here?

When you brought them where they in a tank with fish? I am lucky enough to have a LFS that keep there snails/crabs and coral in a separate tank away from fish and on a different filtration system.

I have to assume not, unfortunately. My LFS specializes in selling disease-infested fish, and they're better at it than anyone I've ever encountered, so I have to purchase all my livestock online. I'd pay 3X as much for a cleanup crew that came from a purely fallow system - no question.

I would go at least the 90 days to eliminate almost everything. Only worry would be uronema. Just have to pray and keep your fingers cross.

Same here, Well one of them anyways lol. I asked the same question about Macro Algae, Pretty much got the same answers.
However I contacted K&P and they keep inverts and macro algae seperate from fishes. Plus they sent a few extra hermits just in case any didn't survive. They all have.
Will be ordering more from them.

Oh, and I got a cool little Oddball Ricordia that is looking good, Lime green and purple.

Yeah, I think in practical terms, there's no way to trust any vendor, even if they claim it's a fishless system. All it takes is someone to have a hand/arm in a contaminated tank, who then sticks that hand/arm into the "fishless" system, and there's your infestation.
