Hi guys... I currently keep a trio (one male with two females) of Pseudanthias squampinnis (commonly known as lyretail anthias) in my 54 corner
thread here , and a pair of Pseudanthias bartlettorum (Bartlett's anthias) in my 65 sps reef
thread here .
There are many keys to keeping anthias. The first I should mention is the species you select. Anthias run from fairly adaptable to nearly impossible, and many of these species appear similar. While beauty is in the eye of the beholder, the two species I chose (two of the most adaptable to captivity) are also beautiful. Do strong research on the species you choose. As soon as my house is built my 180 will go up along with my other systems, and one of the species will go in the 180 and I will increase the number of females. I am in the process of planning my dream tank with the room already be built into the house now, but this ~520 gallon system is still a couple of years down the road as I want to invest in quality equipment. When this system is complete I am considering adding shoals of both species, as Bartlett's and squamipinnis appear to mix well in large reefs.
I strongly recommend Scott Michael's Reef Fishes volume one book, which has a great anthias section. The one male to many many females is cited there as it is in other places, but after observing many systems with less females of these particular species I've tried this with success.
If you have a decent size tank I'd strongly recommend gettong a shoal of just one species, as opposed to a mix of many species. Seeing a shoal of one species interact is fantastic and natural, and truly adds beauty and movement to a large reef as these fish are always showing themselves under the correct conditions. I've never seen a mix of one each of five species as you mention Debbie, but my opinion is that on top of it not looking natural, there would be endless quarells between males of the different species and instead of a well organized shoal with little aggression you'd have a disorganized jumble of different species. As I said I have not seen this tried before, but the beauty of a shoal of one male and a bunch of females of one species is a sight that is tough to beat!
One of the basic needs of anthias is frequent feedings, and again I've experienced this firsthand noticing the thinning of my male squamipinnis. Basically, anthias will not eat that much in one feeding, but rather require a little food more often than alot of food all at once. It's really no big deal, and it benefits all of their tankmates also. I get home from work and defrost some food and feed it in three or four feedings over the course of the night. On the weekends I increase this schedule. Note you're not really increasing the amount you feed too much (a little yes maybe), but rather the smae amount spread out through more feedings. They are not shy feeders as are many picky fish. They duke it out with some feisty feeders in both tanks.
I hope that answers some questions. Do not be intimidated by anthias. They are beautiful fish that can adapt well if you choose good specimens and provide the right conditions meeting their needs. Remember to choose your species well.
Hope that helps...
