You’re going about it the right way. How many times does someone new to saltwater start a tank and the very same day it’s loaded with tons of things. Then everything dies. Brand new tank: first day, uncycled, in goes an anemone, clowns, a tang and a sea apple to top it all off.Clams are very beautiful animals. They actually one of the reason I started this hobby. I had 2 addy different times but they both didn't make it. My tank was still new at the time. Now I'm a loud knowledgeable with a more established tank. Can't wait to get them.
