Margarite snails are from DEEP waters (Gulf of Mexico?) and they need water temps about 50--60F
It's not hard to see how they cook in our reef tanks with temps ranging from 72--80F. Slow boil.
Fish stores should be banned from even selling them. It's inhumane.
IMO-- there ain't a damn snail in the world worth buying for algae control. Mine don't eat it. I've got astrea snails and MIRACULOUSLY 4 margarite snails that have survived for about 8 months. Do they eat algae off my rocks? HELL NO!! I can't use turbos in my tank because the tank is so small. Turbos would be like putting mini bulldozers in my tank. Then I'd have to kill them.
ALL species of snails are very delicate and require extended acclimation times. Like 3hrs MINIMUM. 5--8hrs would be better. They are 99% water. Rapid changes in salinity is the biggest killer. Their blood vessels and kidneys burst from rapid changes in salinity. :shock: They die in a few days/weeks from blood poisoning.
