On Friday, we noticed that Nicka's hermit crab (remember them?) had come out of his/her shell. We figured that it needed a larger home so I cleaned a few shells and put them in the tank. Some hermit crab website (yes, they actually exist. There are quite a few too. Who knew?) recommended to put the shell near the crab so that it has easy climb in access. We did that... except the crab decided to hide under one of the plastic dinosaurs that we put in the tank to liven the place up. Unfortunately, the crab found it's final resting spot under that dinosaur... and now it (the crab... not the dinosaur) is compost in our garden (sorry, no ceremonious burial). I spent a good part of today cleaning out the tank, just in case it was sick or something. Yes, I am a sucker.
