PLEASE don't say anything if you have nothing good to say...this couldn't be further from the truth....It WILL outgrow a 90 gallon tank and if you even try stunting a gar, it won't work and it will be quite cruel. Longnose get like 3' so how do you justify one in an 18" wide tank?? even trops get 24"....
I hope because of you this guy doesn't go out and get one of these fish thinking its ok....I think everyone made it pretty clear there isnt a gar that can go in that tank so why even give him options??
