Hi all, I have a 4inch alligator gar, it will bounce from a 20 long, to a 125 to a 270 then 600. From all I read they reach about 30 inches in 1.5-2 years then slow to anywhere from 1-4 inches of growth yearly. Anyhow, I am building a shop/garage, once it’s complete I will house the 600 in there. What size “pond” will I need to construct for an alligator gar? Would like to run plumbing under the slab as well as a drain. From what I gather alligator gar in captivity have never been recorded near their wild caught sizes, but this could simply be due to their life spans and captive requirements just catching up due to research. Thanks in advance. Was thinking of doing a 10’x 20’ and 3 foot deep. It will also house my cooter turtles. I live in Ohio so outdoors isn’t a option
