my aquarium houses my rock collection from all over the usa and aruba too ect. so that i have created an artificial reef of abalony shells, driftwood,turtle shell and rock. The trick is to not overload the tank with fish...and then you seldom loose a fish. Its a real
comfort in the dead of winter to have live fish in a 55 gallon aquarium to look at. keeps ya from going insane (bigfish)
and a largemouth bass makes a great aquarium fish accept that they eat you out of house and home. I dont have one but have seen many that were 12 inches or bigger in many tanks...
