You always hear about drip acclimating for snails and such..
I brought a bucket of rock home from the LFS on Monday which sat on my deck until yesterday. I pulled the rock out and found a conch on the bottom in about an 1/8" of water. Temps drop to about 10 at night, up to 28 or more mid day and did this for 5 days. It rained and added FW to the mix.
I tossed it in my frag tank and 24 hours later, it's still cruising around.
I won't be drip acclimating anything again
