well anemones care/needs do vary from one species to another (like everything). so instead of getting into a book on anemone care, lets talk about the bubble tip that you are asking about.
anemones are reef invertebrates, like coral, so to keep one you need a reef tank. when i say that, i mean you have to make sure you have a tank thats properly lit, filtered, and you maintain other water conditions as you would in a reef tank.
While all anemones are usually classified as medium to difficult invertebrates i have found that the the bubble tip is one of the easier of the common aquarium anemones, and is a good place to start.
Lighting - i have successfully kept both rose and green bubble tips under
PC lights. i have kept them in a 29 gallon tank with a 130W of 50/50 bulbs. but they will usually not shy away from brighter light.
Feeding - Anemones like food, regular weekly spot feeding of most anything meaty will make them happy. i regularly feed mine raw table shrimp, but they also like clam, squid, silversides, or about anything you can find.
Current - they like moderate current. they need enough current to make there tentacles sway. the reality is if there is too much or not enough, they will move..
Placement - there should be lots of
LR for them to attach to, and should also be placed in a place where they can can retract and be sheltered from light. they are good at finding these spots so dont worry too much. the other thing is you really cant force an anemone to go where you want it, so make sure you pay attention when it moves as it can sting other things in your tank.
hope that helps get you started, if you have more questions just let us know.
