My wife and I are used to the eight Clown loach clicking when there eating there favourite food, but the other day I caught to of my zebra loach eating and fighting over a sinking wafer and I swear it was them clicking.
It was not as ear bursting as the Clown's can anyone else verify that zebra loach click? Or have my Clowns learnt how to throw there clicking

Regards onebto.
