The only experience I have is as a kid I caught a rock fish in a tidel pool at the beach, took in home in a bag and mixed up Morton salt (to spec) in my 10 gallon aquarium and after a week took it to the pet store to sell it and the clerk freaked out told me it was poisonous so I took it back to the tidel pool and let it go. So maybe on a basic level with a little creativity SW doesent have to be too hard or too exspensive.
