Gank. Please stop singleing out members. with so many people on here just because you only know of one person really dosnt mean others dont have valuable information to offer.
We've had both normal ottos and zebra ottos. and wont have any again. I'm an experienced keeper with many other 'sensative' fish. but ottos are something that i have never had success with - we had 8 of each and in both cases they never lasted more than a few months
This was acouple of years back and i keep getting tempted to try again - but the price really isnt worth the risk in my opinion.
