I hope this is the right location for this post, sorry if it isn't...
Anyways, I just picked up two new fish, a 6" labelled as a "mosaic gar" (if I'm not mistaken, it's a type of pike characin?) and a 4" inch unlabeled (got it at needle nose price because they wouldn't listen to me when I said it wasn't a needle nose). I'm pretty certain it's a tropical gar, but want to make sure.
Mostly what I want to know is max size on both and make sure my identification is correct.
