Leo color with odd bite marks?

[dphan5159]

Hello 1 of my 5 leos started showing odd marks yesterday, only around the white spots. Thinking it might be bite marks. Picked up this male 2-3wks ago. Smallest one in group and is only one showing the markings. Water parameters within normal range, added salt prophylaxis. Other than markings it swims around and eats healthy. Tank mates consist of tigrinus, hampala barbs, flagtail, arowana, datnoids, pleco

those are called running spots..not good..poor water quality..once you get water straightened out, the spots will eventually get back to normal in a few months time.
