The exact species is unknown; currently over a foot long, and my friend has three of them. One is, unfortunately, the target of much bullying and is missing part of a front leg. Friend wants to give me the siren; that said, I don't have any open tanks right now, save for a 33 gallon Rubbermaid container. Would this, sponge-filtered powered with duckweed, be all right for temporary housing?
