Perfect for a large tank
I have a 75-gallon goldfish display tank in my living room and it is the centrepiece of the room. Six fancy goldfish in a well-planted, heavily filtered setup. Guests always stop and stare. The fish are interactive, calm, and beautiful. Once you nail the water parameters, goldfish are actually not that hard to keep. I cannot recommend them enough for someone wanting an impressive display aquarium.
