Siner94, some quick advice and I learned the hard way...before messing with your corals clean your hands with alcohol to get anything that can contaminate your water or corals off your hands and then clean them again after you get done messing with them. Some corals, and especially chalices and zoanthids give off a slime when they are stressed out even the least bit. If you was to touch your eyes with out cleaning your hands....even 30 minutes later after your hands have dried, you could give your eyes coral poisoning and it will feel like someone rubbed glass shards in your eyes for about 3 days. I learned the hard way....even tho I was warned about it as well. Nothing like learning something on your own.
