Yes, I constructed the water wheel from scratch with help of my father who's carpenter. The wood is pine and it has a treatment to not rot. I google those fish and i really like alligator gar, however catfish are very agressive. 1 question for you, what kind of reptiles do you have?
HP (I hope you don't mind if I shorten your handle to HP)
I have no reptiles at this time, but I have had the privilege of entertaining the following reptiles: Five and Six lined skinks, Blue tailed skinks, common snapping turtles, green iguanas, painted turtles, red slider turtles, prairie rattle snakes, , box tortoises, cottonmouth snakes, green anoles, true chamelions, garter snakes, fox snakes, corn snakes, bull snakes, and softshell turtles. I might remember more, but my absolute favorites were the Western Hognose snake and the Indigo Black Snake. Many others, but most all were local North American reptiles and caught in the wild. The only exotic species I bought was the Green Iguana. I named him Saint Ignatius. He was 10-12 inches long when I bought him from a pet store, he grew to 4 1/2 feet long before he passed away.
The American Western Hognose snake is one of the best reptiles that you could possibly have for a pet. They do not grow large, so no problem there. What is unique about these snakes is that they like people. Puppies like people. These snakes are affectionate in the same manner. I do not joke here, this little snake that I traded a buddy of mine a pet white rabbit for stayed with me for years and provided me with a great learning experience.
No joking here, I let this Hognose snake crawl around on the couch while I was watching TV and it didn't leave my company. It would explore the world, but would always come back to my midst. Maybe because it was smart and knew where the food was, but I think it actually grew attached to me personally. This little snake would slither around my neck, crawl down my shirt and into my pocket or just point his little face straight at me. Maybe I just have a way with animals, but this little snake was my friend for many years.
