1. Sweet coral selection!!
2. ALWAYS dip your corals - ive seen soooo many flatworms fall off during dipping that im convinced. Depending on where u ordered from, they may be "cleaner" than other places. Dip exactly per bottle instructions.
3. I use a wood-shaving kit I got on Amazon for like $7. Its great to get zoas off plugs. All others, I usually just use bone cutters/hardware store bolt cutters to remove as much plug as i can. The less of the plug that goes into your system, the better chance you have avoiding pests like nuisance algae or aptaisia.
4. Ive always put them on the sandbed for a day, then slowly worked them to desired location (I run G5 Radions that could burn them up, and I don't like the "acclimation mode".
5. I use superglue, just a couple drops to hold it in place. No more. Just in case you end up needing to move it. And, pro tip, you may need to work the frag back and forth in twisting motion to get the glue "bubble" to break under water and grab hold of the rockwork. I usually do.
5. Take it slow, and enjoy your new pets. May take a few days for them to open fully and be happy.
Good luck and Happy Reefing!!
