Im just double checking something, because Im 90% sure that this is not true... I was at my local fish store and one of the employees (who I know really well) started talking to me and we came across the topic of discus. You see I would love to have some discus in my 46 gallon tank. (Its really well established 3 years) and I thought it was too small because you need at least 5 discus (right?) but he said you could keep a pair in the tank no problem.... So now I don't know what to think... Is it possible that the guy was just trying to sell me stuff? I really don't feel like that would be the case though considering its a small aquarium only shop with dedicated staff. The staff member I was taking to has at least 12 fish tanks that I am aware of including one 800 Gal... he just doesn't seem like the kind of guy to try and sell you a fish just for the money.
