hey, i have been looking around for a nice stonehenge model for my tank and came across this on ebay: http://cgi.ebay.com.au/Stonehenge-M...emQQptZLH_DefaultDomain_0?hash=item56340a91d8 would this be suitable for a marine tank? i dont know much about what chemicals etc are safe (as far as this kind of thing goes anyway) and i think it would look very cool to have something as otherworldly as an octopus crawling over it. my tank is 6x2x2 if that matters, and im planning on getting an abdopus aculeatus next, but living on the coast in australia im not sure what ill manage to find. does anyone knows where i could get a similar piece designed for an aquarium? id prefer it as it current looks but have only found restored versions so far. i already have a large (2 foot) air craft carrier that my old octopus used to hide in, and a small but impressive looking pirate ship, but id really like to have this (or something like it) as a real centrepiece.
