god, I LOVE my zebra otos. but, yes, they need to be with other oto friends. And, they are very delicate fish - usually people get more 'dead' otos than live ones in putting them in their tanks.
They are very finicky eaters - they usually come from the store already starving - they eat only certain types of algae, and some 'cooked' veggies. They don't really just pick up other fishes left overs - nor do they like algae tablets.
They're either really well loved, with owners that make huge efforts to keep them alive (which only sometimes works) - or they're in a little baggie in the freezer waiting to be buried...
