Slingjaw Shloop Fish gif
Adam Rifkin stashed this in Fishies!
my boys are calling it "vacuum fish."
It's called a slingjaw wrasse:
This kind of fish can be colorful: http://en.wikipedia.org/wiki/Sling-jaw_wrasse
dude, if i ever get a saltwater fish tank, i will have to get one of those! nonstop entertainment!
Note that you can only have one per tank as they prefer the company of fish other than other slingjaws:
awww... like my beautiful lonely betta.
Heh. You can keep other fish with a slingjaw as long as there's no second slingjaw.
Makes me wonder how they reproduce.
