I don’t have any but also have been considering them for a long time. I think the big issue is food and swimming space. They need to be fed several times a day. I recently bought an Apex Controller so I can monitor my tank while I’m in the Philippines in March. Last time I went on a dive trip and left my husband in charge we had a power outage which killed my return pump. Not my husband’s fault but it would be nice if I could turn things off from anyplace in the world instead of working by text and photos. I also bought the apex auto feeder which works amazingly. I can set the feeding times from my iPad. Because of that feeder, I am seriously considering giving anthea a shot next time I see a nice trio on DD.
