I've got one...be glad to get rid of it for a decent price too Stupid me went and bought one only to find out it was a lot bigger then it looked when I went to put in my twelve gallon eclipse.
*Snicker*
Being a man, I refused to admit I was wrong and proceeded to cram it into the tank. I made it fit too, by god! All it took was some time and patience in manuevering it Of course, now I've fallen in love with the more natural driftwood look, but I'm loath to replace the castle because I spent so much on it
Heh, anyway, the moral of this ramble is don't try to eyeball the size of your decorations versus the actually size of your tank. It doesn't work
Be careful what kind of ceramics you put in your aquarium. Some are safe, but others have glazes that contain metals that will leech out into the water and poison your fish.
I love seeing a castle in an aquarium! I hope you find a nice one!
