I am assumming that you are referring to E.Quadricolor,commonly known as the Bubbletip anemone(BTA for short). The rose anemone is just a color type of E.Quadricolor. They like bright light. At least 2 55watt PCs on a 29/30 gallon tank. But I would recommend 2 96watt PCs instead. Larger tanks would require stronger light. I use 380 watts of VHO(2x50/50 and 2 actinic) on my 55. In just over a year she had 6 offspring.
They also need to be fed about once a week. More feedings may cause her to reproduce or regurgitate. They also seem to appreciate iodine supplementation. I feed silversides and krill. Some have had success feeding clams or squid.
Water motion is also important. BTAs like a moderate current and dislike direct current. Direct current will make her move around. BTAs also like their foot to be hidden. When putting a BTA into a tank you can usually hamper wandering by putting it into a crevace where she can attach and move up to the light as needed. DO NOT MOVE an anemone unless she is in danger of being injured(powerhead or heater). If you must move her try to move the whole rock,as moving may damage her foot.
Be aware that BTAs have pred
ators like large bristleworms,butterfly fishes,and some crabs. Make sure they are not present or are removed prior to adding a BTA.
If you are to add a clown fish,it is usually better to add them after the anemone is settled. Some clowns harass anemones to the point of detachment. It commonly occurs when a new anemone is introduced.
Water parameters are also important. A stable temperature of 78-83 degrees F are a safe range for BTAs. A S.G. of 1.024-1.026 is optimum. The PH should be 8.1-8.4 and be kept stable.
Be aware that anemones are mobile and that they will sting or be stung by other corals. Do some reading on compatable specimens.
Good Luck
