Hermit crabs

    I want to put a couple hermit crabs in my 29 gallon tank. In researching hermit crabs I keep seeing what looks to be a need to put additaves into the water. Is this the case or would they be fine without special attention?

    Hi, welcome to Fishlore :;hi1

    Can you be more specific as to what additives/supplements are being suggested?

    Hermits should be fine without the need for supplements.

    EDIT: But you do need to provide them with larger shells to move into as they grow ;)

    Thank you. Here is something I found on liveaquaria.com on hermit crabs. Under "supplements" there are some things it looks like they suggest adding these to the water??

    Care Level: Easy
    Temperament: Peaceful
    Reef Compatible: Yes
    Water Conditions: 72-78° F, dKH 8-12, pH 8.1-8.4, sg 1.023-1.025
    Max. Size: 2"
    Color Form: Blue, Orange, Tan
    Diet: Omnivore
    Supplements: Calcium, Magnesium, Iodine, Trace Elements
    Compatibility: View Chart
    Origin: Hawaiian Islands
    Family: Diogenidae

    Ah, ok.
    Calcium and Magnesium are the major elements for reef health.
    Iodine and Trace elements are also essential to the health of a reef.

    All of these elements are generally replaced with water changes. If you have a high demand reef system (SPS corals), it may be necessary to supplement the tank with Calcium and Magnesium, but otherwise, regular water changes (10% per week) should be enough to maintain the elements at the necessary levels.

    Is your 29G full marine or still brackish? Hermits need full marine to survive.

    It is still brakish, 1.015. I plan to raise it to full marine though. Then I would like some hermits.
    Thanks, I was confused. I havent gotten into coral yet so a lot of the chemistry stuff I havent got a clue..

    What will you do with the GSP?

    Brackish vs Marine is a fair step in salinity
  7. meplingNew MemberMember

    When the GSP is an adult he will live in marine conditions. All the research I've done says they thrive in full marine.

    I know the conversion has to be a slow one cuz juvie GSP can go into shock if the salinity is rised to quick.
