This is not related to the 150, but I don't have a thread for the nano so I am going to share here.
This evening when I went to feed the nano I noticed that the tomato clown was. He's the sole occupant so it was obvious that he wasn't in there. I was so sad as I realized that he must have died. He was doing so well in his own little world. I looked all over for him and since there are no crabs in there I figured he must be decaying under the rock. I moved everything on the shelf above the cube so that I could remove that shelf from the bookcase and open the lid all the way up and search under the rock for his carcass. I then decided that even though I didn't think it was possible for him to have jumped over into the rear compartment to stick my head into the bookcase and look. There he was, swimming in the center compartment. I couldn't think of a way to get him out short of draining the tank so I decided to finish something I was doing for my daughter and then post on here for ideas.
Chore done I decided to ask for advice when I had a thought....my brine shrimp net. Turns out a brine shrimp net is the perfect size for fishing a clown fish out of the rear compartment of a JBJ 12G nano! Yay. He is swimming all over the tank now, probably thinking to himself "Wow, this place is huge. I hope she doesn't throw me back into the closet."
