They’re, eh, two to three inches long and they live in little shallow stream areas. They need a current going across them. So you could put ’em in a 400 gallon aquarium, but they didn’t have the stimulation of that water flowing past them. They, they actually orient up into the current and they’ll hide behind a rock when they wanna rest. But I was able to extend a water intake pipe down to the bottom and direct a current across the bottom to the point that they exhibited natural behaviors. And that’s what we’re looking for. We’re trying to get the animals to be comfortable in the exhibit. Certainly providing hiding areas, but trying to create an environment in which the animal can act in a natural way based on the species.
