Yeah, they are, and I guess I'd be a disaster in the wrong hands, fortunately I got some good experience with plastic tubs for bringing up fry and small baby fishes. They'll probably be there for at least 2 more weeks, then I'll transfer them to a 75gal then a 250gal and eventually to the pond with the arapaima.Are these fish in a plastic storage tub? That's not going to work. That's a disaster in the making.
