temp 82
salinity 1.024 to 1.025

Ok, I found your hermit crab. It's called the hawaiian zebra hermit, and they are great scavengers and algae eaters, but also quite aggressive with any other crabs or shrimp in the tank. If the only things you're keeping in this tank is the 1 clown and the 1 hermit, I don't see where there would be any issues.
With such a coarse substrate, its going to have a very difficult time in finding food. The large claw is used for a number of purposes, such as displaying during mating, protection by blocking the opening of its shell from predators, etc, but it is not used for feeding. You will probably not really see it eat, even if you watch. Being primarily an algae eater and scavenger it relies on dropped food from the other fish to feed... if that food drops into the substrate showing in the picture it will fall between the pebbles where the crab won't have access to it. I would strongly suggest changing over to a sand bed. If you need help on how easiest and safest to do this, let me know and I can talk you through it. It really isn't such a hard thing

As for your clown fish... I asked my husband to take a look at your picture, and he is thinking either hexamita or lymphocystis. If it's hexamita, it will look almost like a small white protrustion sticking out of a hole in the fish's body. Think of toothpaste coming out of a tube. If it's lymphocystis, it will look like cottage cheese stuck to the fish. Lymphocystis is a viral infection and the only cure I'm aware of is the stings of a condylactis anemone. (yes, you could add one to that tank if you replace the substrate with sand). Only the condylactus anemone is known for helping to cure lymphocystis, and most other anemones will be too large for a 12 gallon nano. If it's hexamita, metronidazole can be used to coat the food while carbon is running in the filter. This will allow the clown to eat the medication without treating the whole tank, which would kill the crab and any other inverts in there.
If you're planning to keep saltwater with inverts and fish, it's a good idea to get a 10 gallon tank to use for quarantine in case a fish needs treatment. Medications will wipe out an invert population very very fast, which will also pollute the tank and make the situation worse and more difficult to clean up afterwards.

Here is a link I found with accurate information about your crab:

I hope this helps!

Get yourself a couple of fish safe buckets (never had chemicals or cleaners in them... most hardware stores sell them in 3 & 6 gallon sizes for cheap). Rinse the buckets good with just water. Using a siphon hose (just a plain gravel vac hose long enough to reach easily from tank to bucket without a lot of extra). Do a siphon, getting the hose directly into your gravel bed, sucking all of the gravel into the bucket. When the bucket is 1/2 full of water, stop, pour the water back into the tank, leaving the gravel in the bucket. Continue until all of the gravel has been siphoned into the buckets.
Get yourself a bag of live sand (have this read when you take out the gravel) and open 1/3 of the top of hte bag. Pour off any water that may have settled in the bag, then pour sand into the tank. When putting the sand into the tank the water will get cloudy, let it settle on its own, it won't hurt your animals. Pour all of the sand in one place, then use your hand to push it around the base pieces of rock to anchor them and cover the bottom of the tank. If you need any water to top off the tank, do that after the sand is in the tank. Let the tank sit with everything running as normal, it should clear within 24 - 48 hrs. Once clear you can move things around to slope your substrate, better anchor any rock, etc.

In that size of a tank you should be able to do this in about 30 minutes, at most. The last one changed over was a 72 bowfront, and it took about 1 hr. If the substrate you are removing is crushed coral, cap the bucket(s) and use the coral to add in a pouch to your filter to help mainatin a good calcium level. Over time the coral will break down, simply add more to the pouch. This way the crushed coral isn't wasted.

Let me know if you need more help!

If I might add to what Dawn provided about adding the sand, If you plan on using Aragonite sand, I would highly recommend rinsing the sand thouroughly before adding it to the tank. Cloudiness from Aragonite sand will settle onto the glass and can become very difficult to clean if it sits there for any length of time.

Take the sand, a few cups at a time, in a 5 gallon pail, run water into the pail, stir the sand by hand while the water overflows from the bucket. Continue this until the water runs clear.

Thanks for all the help. I also had a question about the water levels in my tank, its reading kind of high. How much water changes a week do you think I should do to get levels back to normal?

Please do not rinse live sand before putting it into the tank. The whole purpose behind it is the bacteria culture already alive in the bag. If you rinse this with clean water you will destroy the bacteria culture, which defeats the biggest purpose in using it.
The sand I was referring to is called AragAlive and it's put out by Carib Sea. It is bagged wet, should not be rinsed, and the cloudy water will clear in about 24 hrs with little to no residue on the glass. If you notice any on the glass, it's easily wiped out with either your hand or a fish safe scrubbie pad.

The benefits of the live sand far outweigh the few minutes it may tank to wipe a bit of residue from the glass.

So, I think itís that lymphocystis virus because it looks sorta like cottage cheese on him but it looks like it went away a little but you said the only real cure is if I get anemones. I could do that plus I wanted to get sand in the tanks I think it looks a lot better with live rock and anemones but can it be done with such a small tank, My 12G nano cube? Iíve seen it before in the local pet stores. Can the clown still survive with that virus or is something that is highly contagious?
Thanks for all the help.

No, you misunderstand my intent. I'm referring to plain Aragonite sand, NOT Live sand. Obviously rinsing live sand would defeat its purpose.

Personally, I think packaged "Live" sand is a waste of money. If you are looking to speed up the process of seeding new substrate, Try adding some sand from a friends established SW system to plain aragonite sand. It will add to the biodiversity of your substrate, and save a bit from your purse..

Well, Scratch getting the live rock and stuff. Local law prohibits you taking or even selling live organisms from the ocean. I thought it would be illegal to take something straight from the ocean but I thought it wouldnít be illegal to sell something in a store that wasnít from Hawaii. I had no idea about this because I was in California for the past 5 years . this blows..
