I just really like the looks of them. I like a nice crisp purple color in the tank. I can get them for around $10 a polyp with isnt too bad.
Here are a few more pics I just took
first is the purple zoas again. not a good pic. I moved them to a spot they didnt like so got mad at me so I moved em again. Hopefully I can snag an open pic tomorrow
second is brown / whitish palys... also my new avatar!
All these pics can also be found in my diary in the nano thread.
