I have had my shark well over a year now and he is probably about 18 inches long. Not too long ago, maybe like last week, some times when he swims he kind of twitches and continues on swimming again. Sometimes it is rare for him to do it but I saw him doing it twice this morning and was curious on what this might be. His skin color is way too hard to see if he has any ich spots b/c his body color is a light grey and white. But is this a sign of some parasite (maybe ich)? Should I treat the tank?
