during the warmer months my 8" highfin pleco has the 125g all to himself. Seems to like it. Also the smallest fist in the 6000g pond (18foot round) are 5" they're not alone in there however.
Sold to a guy with a 10' tank. He was already too large for that tank but also I'm moving so i need to scale down on the numbers of tanks i have. The goldfish was my girlfriends sisters and is over 10 years old. I will only have a goldfish tank and my 180g
