Otos don't really do well in a new tank. If you do decide to add otos be very careful acclimating them. I took twice the usual time acclimating mine and only lost 1. I floated the bag for an half hour and then added about half cup of tank water every 30 minutes after doing this 3 times I adding a full cup of tank water every 30 minutes 2 times. After 30 minutes I added them to the tank.
They really do prefer an established tank though.
just curious, but how long was it after you added them that you lost the one? i just got 3 otos about a week ago and they're all doing really well pigging out on my algae.
