My wife has hinted towards getting our young'n an aquarium and I told her only if we could stock it with native fish. It might be a little more work but I'll bet observing a LMB sure beats watching guppies multiply. On second thought, we might stock it with a pair of guppies first then throw a LMB in with 'em. I can get all the dinks I want from my old mans pond. In the 20 years he's had it the biggest bass caught might have weighed a pound and a half.
My brother came up with the perfect solution (by accident I might add) to cleaning any and all fish from an aquarium. He put what he thought was a mudcat/bullhead in with his few perch and one bass. After returning from a weekend fishing trip, he went to check on his fish and all he had left was a well fed yellercat.
