I'm relatively new to these kinds of fish but i was looking in to getting a gar in the future. i've had a lot of smaller fish in the past (Sharks, Barbs, things of that nature). My friend worked at a pet store and brought home an alligator gar for a while and it intrigued me. i've looked into it and i know that they need around 75 gallons to turn around and swim but ive seen some smaller gars that only get to around 8-12 inches. Would a smaller gar need as much as a bigger gar such as the florida or alligator gar? i'm looking to get around a 75 gallon tank and I don't want to spend a whole lot of money on the tank itself. I can not trust the workers at the local pet store because most of them probably dont know what they are talking about and are just trying to get more money out of me. Any piece of advice helps! Thanks!
