To keep one doing well for more than a couple of months, an auto feeder is required and even then, I don't know how long they can be maintained. Mike; Uhuru, here on rc, was in veterinary school here at Ohio State and did very well with many nps types but I haven't seen much from him since he moved back to San Diego. He had some Blueberries that he sold to our local saltwater only lfs, where they slowly faded away. They were incredible specimens when they got there, he did use an auto feeder which he describes here on rc; somewhere but I don't know how long he had them before moving. Hoping he gets back in this segment of the hobby some day. He has a wealth of knowledge and having him here in town was an nps keeper's dream!
