Im looking for some artificial decorations. Most spicifically a purple sea fan, brown staghorn, and black sea urchin. Where have you bought coral & invertabrate replicas from? Ive searched online but have been unable to find exactly what I am looking for. For example, I have found an awesome looking purple sea fan but its 25" tall, which is too large for my tank. I have also haven't found any urchins. Any suggestions? Thanks!
