I have looked over the site and found noone with native darters that has posted selling any. Most native fish don't have to have a licsence to buy. I bought 100 large mouth base for a stock pond last spring. Just by going to the site and ordering them from Texas parks and wildlife. Indangered species is a differnt storie thou. Most you have to check your state importing laws and see if there allowed in your state. Like Texas and a ton of other states don't allow the large bodyed snakeheads and Florida don't allow (I beleave it's the red arowana ) Also new Jersy just banned the bared sunfish from hervisting and home tanks.
