Once again, you failed check the laws of Texas. It must be 18" to legally kept, unless obtained a baby flathead from fish hatchery.pshtex;5146756; said:it is not easy to catch a baby flathead when fishing they are less likely to take the bait than a bigger one i think ur best bet would be go to an area that has flat head and drop down a bait fish trap that won't allow larger fish in it tie on a long line so that trap hits the bottom then go check it the next day rebait and try again
