My Tassle File is just precious! The size of a wheat thin cracker, he is so easy going and peaceful... sweet as 4 cups of sugar. Non-demanding, very smart and gets right in there to feed alongside tankmates 10x his size with no shyness at all. He is a very deliberate eater though. Slowly picking and choosing which morsels to eat. So to ensure his nutrition, I highly recommend feeding Nori seaweed sheets on a clip. My Tassle finds the nightly dried algae treat soothing, as he will attach his mouth to the algae and literally suck on the side for a good hour, sometimes two. It's like putting a baby to bed with a bottle! So adorable to watch.
