My crab has scratchy black spots on it.

[Chocobo]

I've never seen this happen before.

[PinchersAndShells]

Can you get pictures of it?

[GotButterflies]

I agree. Can you please post a picture? You might need to use Tapatalk.

[Chocobo]

I can't post images until the hurricane stops messing up the wifi, and it's going to be a google photos link because I'm not going go through [insert large description here] just to post images when every single other website with image sharing lets you do it so easily

[GotButterflies]

Stay safe. That is top priority.

[CrabbyLover77]

Not sure if any of this will help, but I found some old HCA posts about black spots on crabs and treatment.

I am able to view this picture. It looks like shell rot to me. If so, it is contagious. Please PM Wodesorel and ask for her to view this post to get her opinion as well. If so, you need to do the medicinal bath that is recommended.

Do I have to do a deep clean on the tank? Do I also need to disinfect everything in the tank? will giving the crab a saltwater bath work?

[Chocobo]

These are two other crabs I'm wondering about:

and this one

I copied this from another post. I think you have to isolate the crabs to treat this, but I'm not positive. I do know that it is contagious. Once again, DM Wodesorel and ask her to look at your pictures. You can get these products at a Health food store.


Herbs for wash can be purchased through the Hermit Crab Addiction store

This recipe can be modified, made stronger for use with very sick crabs,
although this strength is fine for more minor cases!

General wash for injured crabs:
1 Tbsp. Marshmallow root shaved
1 Tbsp. myrrh powder
1 Tbsp. calendula (marigold)
1 Tbsp. whole chamomile flowers (not powdered)

First, you'll need to make a decoction. Take one quart of water, and heat it
over the stove to near boiling. Add one tablespoon marshmallow root, and one
tablespoon myrrh. Cover, and simmer for thirty minutes. Remove from heat.
Add one tablespoon calendula flowers (marigold) and one tablespoon whole
chamomile flowers. Cover immediately again. Let sit until cool, then strain
herbs out and refrigerate. It will last a max of 48 hours. The herbs are all
safe, they can even be fed to the crabs. I routinely feed calendula and
chamomile to mine.

When bathing the crabs, bathe the affected parts only. I don't see any
need to get the stuff on the gills, unless there is an infection of the
abdomen. The reason I say this, the marshmallow root makes a slime coat,
which is sort of thick, and is not beneficial in the shell unless you're
fighting an infection in that area.

These are some of the general benefits of these herbs:

So marshmallow root draws out infections, draws out splinters, and makes a
thick slime coat layer that helps prevent infection and aids in healing.

Myrrh powder (like what was given to Baby Jesus), is a powerful
anti-bacterial, yet unlike antibiotics, is completely safe for crustaceans.

Calendula flowers (marigold), gently stimulates the immune system, is a mild anti-bacterial and anti-fungal, and cuts down on healing time.

Chamomile flowers, reduces inflammation, helps to speed healing, and reduces
swelling when it is present.

A few words of caution: do not use powdered herbs; you really need to find
the bulk medicinal herbs, because too many properties evaporate when the
herbs are crushed. If you drink chamomile tea, and do not find it that
relaxing, you should try a cup made from the whole flowers. There is a
noticeable difference.

And second, all the properties of chamomile (the essential oils) evaporate
with the steam. That's why, when cooking herbs that have any essential oils,
you must trap all the steam and let it cool, so the medicinal contents will
remain in the formula.

_____________________________________________________________

Specific Wash for Bacterial Infection (including shell rot if caught in early stage):


Note: my Vet said to put crab in clean substrate (preferably sand) and maintain humidity at exactly 70% (apparently lower humidity retards the metabolic rate of the bacteria, and this is the lowest a crab can tolerate while being treated) and more light. *this is a case for separate isolation!

2 cups dechlorinated water
1 Tbsp. myrrh powder
2-3 Tbsp. calendula (marigold)
1 Tbsp. whole chamomile flowers (not powdered)

This concoction should be steeped after the water is boiled. Let it sit for about 20 minutes, strain out petals. Wash should be applied 2 times a day for 3 days, let the crab sit in it as there may be lesions on his shield and abdomen. It will benefit him if he retains it as shell water. After the first few days if you notice more lesions forming or see more discolored depressions in his chitin, you may not be able to stop the progression of the disease. If you do notice that there is no more formations, change out the substrate for new and watch him in ISO for at least another week. You can repeat the process again if you see reformation occurring. I think it would be up to you if you want to continue, but remember to keep this crab separate until you are sure that he has no active growth of the bacteria on him. With my indo BOB, he remained in a 2.5gal ISO until he molted.

I pm'd her last night. will fish antibiotics, turtle fix or reptile skin spray also work for the crab? I saw other people mention that. If not, do people online with hermit crabs sell these things?

[GotButterflies]

Nobody knows how fish antibiotics work with crabs. As far as the individual items, I sell everything in my store except for the myrrh powder. My store is on vacation right now. There might be others that do as well. I really think you would be better to go to a health food store to get them so you could get started on them asap. I'm glad that you caught this!
