Hey, nothing wrong with otos. I LOVE them. They're full of personality and when you look at them close-up they are quite adorable. So I disagree with EndGame over that. A few weeks ago, I would have voted wholeheartedly for otos, but they are just soooo sensitive. I blush (and cry) to think how many I've lost in the week or two after I get them from a store--and as Brendan said, this is not uncommon at all.
If you get 10 otos, you have a good chance of having 1 or 2 left after a month. The survival rate is so pitifully low... This may not be the case in other parts of the country or in other countries... Just my experience on the East Coast, and just what a lot of others have reported about their otos.
Still, I vote for the Bushy Noses. With these, look for a place that will offer you a good selection. Some of them have very ugly yellow-brown color, while others are quite elegantly brown-black. Also, look for the active and slightly older specimens. These are the most likely to survive.
