This is a small group of fish called "TinyFish v2 - School 1". These are colored orange and white and are constantly moving - thought just bobbing around and flitting their tales. According to the mesher, MadN: "Tiny Fish schools are groups of Tiny Fish v1, v2 and v3. They have a life of their own and come in two types:"school 1" which is this group of fish that bobs in one spot randomly, and "school 2" which is a school that swims in a circle. Both varieties of Tiny Fish schools have random animations. These schools of fish have small file sizes, so you can add in one school and then copy it over and over again to bring your underwater room to life. Because of these small file sizes you won't slow down your chat even if you place 100s of fish into your room."
