The pond is about a 1/2 mile from the Rio Grande River. So it makes alot of sense..I wanted to use this smaller pond as a bream pond and didn't want to put any bass in untill i grew them 8lbs or better from my larger pond..do u think these tetras will help control the bream population in the mean time? that brings up something else, i have yet to see a single bream or fathead minnow that i stocked a couple mths ago? theres tons of gambusia..Do u thing those tetras ganged up and ate my 2-3in CNBG adn 3-4in fatheads?
