Hongsan Sujogwan is a tropical fish shop in Seogyo-dong, Hongdae, selling guppies, shrimp, turtles and aquarium plants. It carries large plants along with various fish species and supplies, and builds aquascape tank layouts on site. Staff explain fish care and breeding methods when asked, pack livestock carefully, and sell supplies in smaller portions. The store is small, so wait times grow when many customers are inside.
