thanks everyone, and thanks hollygirl for the photos. sorry about the duplicate post, I'm not too savvy when it comes to posting ( and computers in general) I tried to delete the second post, but could'nt do it.
I've had difficulty getting Otos on a prepared diet too, you may have to give them away. You could try some Zucchini or other vegetables, other possibilities would be food algae wafers.
Besides fresh zucchini, which they get 2 or 3 times a week, my ottos like spirulina pellets and Hikari algae wafers. They also like an occasional fresh spinach leaf. Good luck.
