Do Corries go into hibernation?

[Crumbs]

I have several Tiger Cories in my tank and sometimes they will not move for two weeks. They still stay alive but is something wrong with them? I have thrown one out in the past. I have another one that has moved 2 inches in two weeks. Here is a pic of the snail to confirm its identity.

Everything else in the tank is well and healthy with over-filtration and frequent water changes. I heard the snails prefer cold water. My temp is maintained at 68 deg.

Well that is where the problem is. Cowries are tropical. Try raising the temp a few degrees a day and they will become more active. I keep my tank around 110-115 degrees F. I have problems cleaning the tank because my skin sloughs off from burns, no just kidding. I kept two cowries (tiger) and (chestnut) at 78 degrees did just fine.

Awesome shark btw!

Thanks for the reply boomsticks,

The thing is that the rest of the snails are all active an healthy. I dont think it is the temp that is affecting them. Not sure what else to say, I thought it may be a natural cycle of dormancy.

Actually Crumbs, it very well could be. I never thought of that the snails are out competing the cowries! Interesting.....

By the looks of the picture you definately do not have a Tiger Cowry (C.Tigris). What you have is in the family of the Reticulated cowry - a group of several different cowries that look almost identical making I.D. rather difficult (C.Reticulata,C.Arabica,C.Maculifera and so on)
The good news is they are probably less predatory than a true C.Tigris,feeding mainly on algae. You should have no difficulty keeping them in a well established reef aquaria. I've kept similar specimens for several years.:rollface:
Good luck to you!!
