Scorpion Fish Or Yip-Yips?

I don't know if anyone else remembers the Yip-Yips from Sesame Street but they were little creatures from outer space who would travel to Sesame Street in their spaceship....anyway, the fish in the background reminds me of  them because of his big eye. These are Plumed Scorpion Fish and they live in a small tank in the FAU Research Gallery at The Gumbo Limbo Nature Center in Boca Raton, Florida...
