i really nid help guys..today i went to the petshop here in phillipines because im gonna look for garter snakes...so i saw a garter snkes but it cost 4 dollars each(adult) an dthen i refused it then another owner asked me if i want a snke called a "Water Boa" and they said that its a harmless snake and it cost only 2 dollars each but when i looked at the snake i saw the snall snake about 12inches long and a big body really looks like a ANACONA(the huge snake )but i only want is a maybe a 30''inch snake for a pet not a 20feet snake i looked up in the internet what is a "water boa" is and i saw it in the internet that "water boa" means ANACONA but anacondas lives in the western side of the world not here in the phillipines so why are they selling it in a really low price ..lower than the garter...so i hope when i buy that snake it will not grow being a monster size pet but a 24''inch pet. so help me guys what is a water boa?? (may be the pet owner is wrong about the name)
