Snails
 

Hey everyone,
I just got back from being away for a few days and noticed that a hermit crab was going after my large snails and in the end killed a few snails. Would this be cause by not having enough food or not a large enough shell?

Thanks for your input.

It's a hermit crab thing. I think they're after the shells.

They can be bullies. I had to break up a few fights with mine before i got rid of the hermits. Im not sure if its because of shell size or not. Sometimes i think they just want a few to choose from in the morning.

Yeah It kinda seems that they just want ten shells just sitting there waiting for them. Is there anything else that you could suggest to clean up the sand bed that won't kill my snails?

I've got a couple of wrasses that sleep in the sand, they stir it up well. And a couple of orange spot gobies to sift and spit sand everywhere

Yeah that might be a better option for my tank, I will see about picking one up next week and see how it does.

How deep is your sand bed?

I have a pair of yellow headed gobys. They do an awesome job of keeping the sand clean, but they spit sand over everything you have.. So at least once a day you have to blow sand off the corals.

Its around 1 inch or so.

If your sand bed is only that deep, honestly the best way to keep it clean would be manually. Just stir it up once a week, and then suction off the detritus that settles on the top when you do your water changes. If you stay on top of it, it will hopefully not get so bad.
