When I first got my tank I bought 2 rainbow sharks from the LPS simply because they were on sale that week. I quickly found out how aggresive they were to each other (no thanks to the guy that sold me 2 at once and gave me no warning of their temperment). So several months ago I gave one to my dad but that is all he has in his tank, I will be going for a visit soon and wanted to buy something else to put in there. Any info/ideas would be great.
Thanks
P.S. the tank is about 48"x12"x12" (I dont know how many gallons)
