The hardiest hosting anemone is the Bubble Tip. Doesn't matter which color. They'll even live under T12 lights if you feed them often enough. I'm not saying it's a good idea to try it, but in a pinch they will do ok. I used Bubble Tips to teach batches of baby Clownfish to go in the anemones and they were subjected to 100 ppm nitrate and only ambient room lighting for weeks at a time. They handled this fine too. Essentially, as long as a BTA is in good condition to begin with, it can handle a lot of abuse. The Bubble Tip that I still currently have I've had since 2007. It survived a 1200 km (745 mi) tank move, it hung out in my SPS tank for a number of years, it survived many batches of baby Clownfish, and now it's in my new SPS tank. It's not the prettiest RBTA (it's just pink, no fancy rainbow), but it's always bubbly and it's tough as nails.
They have their drawbacks too. Some of them walk around and don't seem to settle. I find if I feed them every once in awhile they are less likely to wander. Some of them split like rabbits and all the little rabbits walk around. Some of them never split and get huge. Then there's the other end of the problem - the Clownfish don't go in them! That's the Clownfish's problem though. :rolleyes: Keep in mind, not all anemone species with host all Clownfish species. BTA's are one of the most universally hosted hosted though, so they make a great choice. IME, True Percula, Onyx Percula, and Darwin Ocellaris are better at being hosted than Orange Ocellaris.
