My pair of pipes will be 2 years old this October. I am not having a problem keeping them alive. I have noticed a lot of reefers posting on different sites (including this one) having trouble keeping them for more than 6 months. Compared to Acropora, Tangs, Clownfish, and the like, there is not a lot of easily accessible info out there on pipefish that I have seen. I'm just trying to help a few people out that are struggling to keep them, but I would like a more complete perspective. I am also just plain curious how many people are trying to keep pipes, and their success' and failures. Thanks so far!
