　　This is the case. I just entered the two black vest clowns, about 1cm in size. I have been swimming with the larger clown in my tank for a long time before I entered the tank. Less than 5 minutes later, the clown in the tank pulled sideways.After two hits, I wouldnt care anymore. When I came back to feed at night, I didnt eat for two days. I still didnt eat. I just separated the two clownfish I just entered. What should I do now?Is there something wrong with these two new ones?The old fish that made me do not eat now, it used to be granules!Very speechless now
