This weed-eating fish has no swim bladder and must continually flap its ventral (lower) fin to remain afloat. When resting, it uses its two anterior (front) fins below the mouth (reduced to simple sticks – only one shown) as “kickstands” to hold itself upright. The spiral over the nose is the olfactory (smell) center and the one on the back is a dorsal fin packed with blood vessels so that it can be used for respiration, as this fish has no true gills, either.
