I guess my Nic had an itch on his eye or gill cover. How did he try to get rid of it, by scratching on a rock or on the sand? Nope, he decided he would try to scratch it with his pectoral fin. He kept bending it forward and shaking it, and continued to do this for five minutes until his little fishy brain told him it would probably be more efficient to do as other fishes do and scratch on the sand. For a while there, he looked more like a dog than a fish.
