Someone named Audrey (hi Audrey!) asked in the comments of an earlier post whether the rainbow fish could be knit in the round to avoid seaming.
It can, although there would be a little jog in each ruffle/fin on the fish's belly (just like stripes knit in the round have a jog in them). However, I think that's the kind of issue that only a knitter would care about! (And not even all of them!)
