I'v been having trouble not only finding livestock for a temperate marine aquarium, but even decent, updated literature on them (this is particularly puzzling to me given the numerous public aquaria that house coldwater species). I have found one good book by Dr. Roland Anderson (Aquarium Husbandry of Pacific Northwest Marine Invertebrates), but have yet to locate material on aquarium critters from the Northeast US, UK/Ireland, South Africa, Tasmania, etc. Even a good website might be helpful. Any suggestions, anyone? Also, does anyone know of collectors/importers that operate in any of these areas? Thanks...
