Logan, I'm so sorry to hear that Otto has gone to the RB.
I remember meeting him when I went to visit you at your house.
He was the first one of your pets to meet me when I came in the front door.
I meant to get a photo of him while I was there but he is the only one of your pets that I didn't get a picture of that day.

I know what you mean about little pets not living long enough, since we lost our gerbil Chocolate in July it was just too empty without her. Since then we have added a hamster and a betta fish to our family.
I have a feeling you may have another betta in your house again soon.
