so, i've seen some Saltwater tanks, and more and more I would like to try one... but what to get as a "starter"? at first I thought snails, cuz I do like them... but they aren't active enough for me to do a whole tank with just snails, and the LFS has a display tank, and they have small red crabs.. I thought it would be really cool to have a small tank with one or two....

SOOOOooo.....if some one could start meh out(i've only done Freshwater )
and basic requirements and equivalent, and the hardiest crab you can think of, along with tips and care, I would greatly appreciate it

(crabs don't need a metal halide light right?)

Well....I wouldn't really do hermit crabs...they're kinda boring...

You could do a and several . the crabs like to scuttle about and the skunk is always showing himself (unlike ) or maybe the more boisterous . You could always host a purple (very pretty).

None of them need more than fluorescent lighting but they'll all need a supplement for iodine to regrow their shells when they molt. They'll eat almost everything and really take care of themselves.

If you do decide only on hermit crabs or the coral banded shrimp do not house any snails with them because they will kill and eat them....very sad...

Okay, let's run with the hermit crab, since that's what you said you wanted.

You don't need RO water for SW. It just helps a lot.
Do you know the type of hermit crab you want to keep? Are you looking for a fully marine one, or one of the land hermits? The Ecuadorian hermit crab needs a mix of land and marine water, and seems to be a pretty active type of crab.
If you're looking for a full marine, I know less about them.

Excellent. Let's run with that species (you can always adjust later if you find a different species you like better).

They grow to be 1.4". They're small. I think the smallest aquarium I'd give one would be a 10 gallon tank, and this would leave space for another small inhabitant, probably. Anything bigger than that would leave space for more inhabitants.
A couple of sites suggest that they don't actually like killing snails, either for new shells or for food. I'm not saying that a snail added would be 100% safe, but I think that, if you provided both adequate shells and adequate algae/seaweed (their favorite food), you might be able to get away with a snail.

Setup isn't all that different from a freshwater aquarium.
Decide on the tank size.
Figure out the equipment you need. My suggestion would be:
Tank itself
Protein skimmer
Hood and light
Powerhead
Sand
Heater (unless you've got another way to keep the water at 72+)
Live rock (or a mix of live and regular rock... the live rock will seed the regular) This isn't necessary, but it makes cycling so much easier. Just cure it in the aquarium and you've completed the cycle.
You don't need (though it doesn't hurt to have) a filter. The rock will provide space for nitrifying bacteria to colonize.

The crabs don't need high-output lighting, but light will produce algae, which will help feed your crab, so don't be afraid to upgrade the lights, if you can. If you're going with a 10g, even just replacing the incandescent tubes with brighter CFLs would be good.

It shouldn't matter too much. These little guys are pretty widely spread and adaptable. Sorry I forgot to include that, but yeah, it's kind of important
70gph should be good for a 10 gallon aquarium.

In a 30-40g, the minimum gph I'd suggest (based on what I've read) would be 180-240.

My money is on that invertebrate tank turning into a fish tank within 3 months.

3 months? that's an insult, I move faster then that >

well if I get that 30G up il have atleast one fishy ^.^(two fishy, three fishy, four fishy more!!)
i'de really LOVE to have a mandarin goby, but I don't think it will happen to soon...

EDIT: almost forgot >.<... don't I need a fairly high PH? like 8+

how would I go about changing my ph from 7.4???

Good morning,

I have moved your thread to the Saltwater Crabs section of the forum.
Thanks!
Ken

I believe the minerals in the salt mix do that for you. What they do is they evaporate sea water and sell you the results, and it's the minerals that raise the pH.
This is the reason that RO helps; if your water is starting with a high mineral content (yours actually is probably low to moderate, since your pH is closer to neutral), and you add the salt mix on top of that, you end up with more mineral than the livestock is used to.

well....that's what acclimation is for ... a bit drastic?

il buy a small salt set... test and see how it turns out.

Probably the smart thing to do.
One of the reasons I don't have any marine tanks yet is because my water starts at 8.2-8.4, with a ton of calcium and other minerals. With my water, it wouldn't just be a matter of acclimation; it would be a matter of the water being significantly more mineral-dense than what the livestock would be able to handle. I could probably get away with a tank of hardy inverts, but fish would be more difficult unless I got an RO set.
