Here's a concept that's dawning on me recently. Vieja with room act very differently from Vieja in a heavily stocked tank. You want to watch all the little intricacies of Vieja behavior as they mature, you'll need to provide them some room to operate, and other Vieja to interact with. I don't get the "wet pet" thing at all, and I definitely wouldn't do it with Vieja. The whole point of having Vieja is watching them interact with each other. But, on the other hand, although you want to have several Vieja in a tank together, you don't want to over crowd them, either. I see some tanks on YT where the owner has OVERstocked the tank, presumably to lessen aggression. That may work, but I think it also defeats the purpose of having Vieja. If they're too crowded, they quit doing all the cool things to each other that make them fun to watch. In particular, though they fight less when crowded, if they do fight, it's a murderous affair as opposed to a careful show of force to test the resolve of the other.
