Soooo... I just got a bubble tip anemone for my almost 2 month tank. And i have been scolded by everyone on here. But i have done the work to keep it. I do 5g water changes once a week. Water parameters are PERFECT. I give him a lil shrimp, he nibbles (or so i think) but doesn't eat much. My fish don't really host, but i have seen them feed him.
My set up though has 65 gallons of filtration for a 38 gallon tank with maybe 29 gallons after displacement, and then a 65 gallon Protein skimmer. But i keep my tank perfect, or as much as i can. It basically has 130 gallons of filtration for 29 gallons of water. I think its to much but ya.
Mine is thriving. Be careful with lighting. I get 4.5 watts with my lunar aqualights, and i run 10ks for around 10 hours. He likes it but near the end it seems like he is getting burned out and starts to shrivel then i flip on actinic and then moonlights and 1 hour later he is spread out again. I'm going to change it to 8 hours a day for 10ks.
I would urge you to .... to... not get him. If your tank is a couple months old and you have the load, and the protection i would say get him. (prob gonna get yelled at for saying that). Mine hasn't really done bad at all. For the first 2 days he was terrible. This was because of stress. He was kept in Low lighting at the fish store, and when i put him in the 10ks he hated it and crawled UNDER the rock. but now he is high on the rock and loving life.
My experience was good, but i would have waiting a little longer for mine. So if your tank doesn't have the qualifications, and you don't wanna do the work, then hold off for a few months.
That was a quote of what i said for another user.
Basically you can get an anemone when you want to take teh responsibilty to care for it. Mine now has doubled in size, eats a full sized krill every other day, and its always fully extended and happy. Its now been 3.5 months (wow didnt realize that long) sense the tank was set up...
I wish you luck on ur decision i say get it
