considering that RES live in ponds and lakes, trust me you can't get anything TOO big for them..

Most experienced keepers would tell you to buy big and buy once. That way you don't have to have a bunch of unused too small of tanks laying around to be filled with something else to take your money. Been there done that. have the fish to prove it..
Just for reference.. a female can grow to be 11".. and a male around 9".. so following the 10 gallons per inch rule, you'd need at the minimum a 110gallon tank. See what I mean by not too big..
