I got a new pet yesterday, my first ever Lionfish. She is a Yellow Dwarf Lionfish, the yellow variant of the Dendrochirus brachypterus. Acclimation was uneventful, in fact, she showed absolutely no fear and was curious about what was going on (I guess I wouldn't be scared, either, if I was so venomous!) She hasn't gone into hiding at all and likes to hang out in the open, calmly watching us walk around the kitchen. She's like a puppy!
Check out Lionfishlair.com run by my good friends Renee and Greg Hix. Most of the photos on the site were taken by Renee, who is the best photographer I've ever met. Her macro shots inspire me to become a better photographer.
