I have been getting rid of tanks, too many, not the right type etc... I have 1 10g qt for fish only since it has a regular florescent bulb on it and have a good spot for it. I am temporarily using my daughters 45g corner tank to dip and qt until december but only recently aquired it. Also a 27 hex fish only which was my other daughters - this may be what I'll use for coral qt after she picks up her fish.Or the 30g that I'm currently using as my sump for frags. Just sold a 100g hex w/center OF and a 24g nano that had no canopy. Almost all my rock I bought dry except a few starter pieces to seed the rest. So I do qt fish but had no place for frags with proper lighting. So I only dipped them and Qt'd for 2 days in a bucket with my tank light flooding into it. I would inspect them and put them in the dt on the frag rack if they looked good. If I saw anything that shouldn't be, I would start over. Until the asternia stars showed up I had pretty good luck. Snails on the otherhad I've never qt'd and was told many times to just put them in the tank. So I did after looking them over. But the pyramids we inside the shell where they couldn't be seen. I didn't know pyramids went after snails untill now, I thought only clams.
The aptasia just appeared one day on one coral I had for more than a year and spread. The pyramids came from a new lfs in Brooksville. As far as the asternia, I know where they came from but too late now.
What kills me as that the tank got all of this at about the same time :/
