I would have to disagree. If you have a 2" fish in a 450 gallon tank the fish may suffer from malnutrition, because of not being able to find the food; especially if there are larger tank mates.aclockworkorange;4685982; said:there is absolutely no harm in keeping a smaller fish in a big tank, as long as it has compatible tank mates.
A small gar in a large tank has the time to build up speed if/when spooked. If it then hits the side of the tank there is the increased risk of the gar breaking its back. In a smaller tank the damage from hitting the side is not as serious.aclockworkorange;4685982; said:Could you please explain the benefits of your "step up" method for housing gar? It just seems like you are running the risk of stunting the fish, and that there is absolutely no harm in keeping a smaller fish in a big tank, as long as it has compatible tank mates.
