so i purchased an asian gar (xenentodon cancila is its real not, its not actually a gar) and the next day after purchasing him i put a whole slew of guppies in there for him and some of the other tank mates, the guppies have been in there for a day and to the best of what ive seen he has totally ignored them, they have literally swam right by his mouth and he hasn't eaten them, should i be concerned do you think? its probably about 6 inches long so i know he has the ability to eat them
