Wait awhile on any anenome and do your research. Depending on your setup your tank is probably just finishing its initial cycle. Patience is the key to success in the SW
hobby. Patience is the hardest part of the hobby for most, me included. If you take it slow you will find SW
keeping much more enjoyable and a lot less costly.
I would wait a full 6 months if not a year before trying another anenome, depending on your setup.
Your mistake is not an uncommon one. I can not guess how many mistakes I made first starting out and the $ wasted not to mention the poor animals that suffered due to my lack of knowledge. I wish I knew about resources like this site when I was starting out. Hang out here and do your reading. AA is a great site to hang out at and learn from others successes as well as mistakes. It can become as addictive as fishkeeping itself.
If you want describe your setup:
Size, equipment, water, filtration, etc. and what you your goals are as far as stocking. I am sure many can help get you pointed in the right direction. There are also a lot of posts you can check out here.
