I just say this because they can be skittish and break their backs easily as I'm sure you know, 24" width doesn't give lots of room for when it gets scared, they also aren't very flexible fish as I'm sure you noticed by nowThanks, I thought the aro was going to improve also.
The gar is almost at max size and it still has plenty of room. As it is a 100% true shortnose gar. It will go into the upgrade, or pond, witch ever is done first. Been kicking around getting a 7' round stock tank for the garage until the outdoor pond or inside tank is done.
