Not too sure but my thinking is it’s either a goldfish (Latin name: Carassius auratus) or other kind of carp (crucian? koi? just carp?) But I know next to nothing about fish anyway so I may be way off
tags: Steven Universe spoilers, a single pale rose spoilers, artie talks, lennat2, I know koi doesn't begin with c but it could be like carp (koi)
