I just noticed this behavior a little while ago…my clown doesn’t seem to be able to close his mouth. Or doesn’t want to. I can’t say if he is eating or not but I should be able to when i feed them this evening. I’ve been out of town for two weeks with a family emergency and have only been back for two days. My tank sitter didn’t mention anything out of the ordinary. I took a couple of videos and pictures. The only thing i can think of is i had my neighbor adding soda ash via 5 ml dropper each day as my doser wasn’t working when i left. I specifically told him to plug in the power head before adding and be very mindful of the fish as I’m pretty sure that stuff can cause some nasty burns. I don’t think he is that reliable but i was in a pinch and didn’t have a choice. Wondering if the clown decided to eat some “white cloud”. Is there anything i can do or try to help the little guy out?? Not sure if the videos are working- i may have to repost in the next message
