Just wondering, because on all these sites I've seen Minum Tank Size: 50 gallons, or something around there. It said ropes could be kept in a 55 gallon. Why does it say this?
When I worked at a fish store we had some rope fish in a 20 gallon. Though, most of the time the tank at fish stores are temporarily, I dont see a problem with a small one in a 20 for the time being.. Most of the time they are lazy, but a tank atleast four times the fish's lengh should be suitable..
