I was so happy to add this beautiful young pair of percula clowns to my fragtank ..I watched them closely ...after turning off the lights I checked on them again with my flashlights but I was too late . An aptaisa , not even that big hid under a rock and tried to swallow my clown. I had to beat the lifeless body out of the mouth, it did not want to let go ...I cannot believe it ...I just want to share this story with everyone , because before i never consider them a real threat to fish , but now I will be on the lookout...i am still shaking and really sadened..please everybody be careful with little fish !!!!!!:
