Brand new Tank/Hermit Crabs Hi, I’ve another 29 gallon marine options than just has been recovering for 5 days today

Its a live rock system. I have checked the water for ammonia, nitrite, PH and salinity, all of which turned out fine but just to be on the safe side I also took a sample of the water to my local marine specialist and again it tested fine. So I bought 5 hermits and 4 snails to help clear the tank of the algal growth that had covered the rocks, glass and bottom of the tank. About 2 hours after I had introduced them I checked on them and 3 of the snails were almost dead on the bottom with the other 2 still on the glass but very weak. Also 3 of the hermits were hanging out of their shells looking dead and the others again weren’t moving around and looked very ill. I immediately took the hermits out of the tank and they seemed to recover a little in the air. The tank has a red algal growth covering the rocks that looks like velvet. Could this be the problem or is something else causing these animals to die?

Remain you to definitely in mind with your own improvements -Paul> Oh and you can many thanks for replying

Dying hermits – The only thing I knew about acclimating was to leave the tank in the bag for a while. Though I have just been informed about slowly adding small amounts of tank water into the bag. The hermits are a reef species so I don’t know if they require air but they didn’t have any in the suppliers tank. The animals had been at the dealer at least a week.

Very a new comer to the fresh new interest

Hermit Crabs My daughter and I found some hermit crabs off the shore of Biloxi, MS. Can you direct me to a location on how we can care fore these in our home? Thanks Dave
