Some points might be helpful for u to choose your anemones
* hard to keep anemones especially, is that they seem to have a very slow metabolism . They are very slow to let us know that they are unhappy and by the time we notice, they may already be too far gone to help them since they are slow to react to beneficial changes too.
** Clownfish host anemones all need lots of light to do well. They obtain most their nutrition from a symbiotic algae (zooxanthellae) that lives inside their tissues. Lots of light means from 3 to 6 watts of bulb per gallon of a standard depth aquarium. That means you need at least 4 of the longest bulbs that you can fit over your tank, usually in a ratio of 50% actinic and 50% full spectrum bulbs.
*** Anemones prefer water free of organic wastes, which in most cases means you need to have an efficient protein skimmer. Maintaining the levels of trace elements in the water by performing regular water changes or the addition of commercially available supplements also seems to be important. Charles Delbeek mentioned that iron supplements could benefit the zooxanthellae in the anemones. I found that the addition of CombiSan (which contains iron) seemed to help my sebae anemone regain its color. Moderate current, in addition to clean water, helps exchange needed elements and rid the anemone of waste products. Some of the more delicate anemones seem to prefer higher temperatures in the range of 78-80 F and pH in a consistent range of 8.2-8.4.
