As some of you might have noticed I'm after a trio of vampire crabs (if you can help me get some pm me). In the mean time what would I need to keep them? I'm not one for ugly tanks so Ideally I'd be wanting to do something like a palladium, live plants and a nice aquascape. Also, I'd imagine I'd need a filter and heater/heatmat? Does anyone know what the smallest internal filter you can buy is, something that can easily been hidden in a scape? Any tips on anything is useful, especially regarding scaping a palladium what plants would be suitable and keeping the tank warm as I'd want to have it open topped. Thanks in advance.
