Appears to be more injury related as opposed to deterioration of the lateral line as commonly seen with HITHHITH maybe. I am not so good with this stuff, but ron Would know
I will change the water every 2 days by 30% let see how it goes.I would do a water change and add aquarium salt and melafix since it looks like an injury
I don't think the hole in the headHITH maybe. I am not so good with this stuff, but ron Would know
Thanks for the reply. I will try to do that water quality. It's best I can tell. Well, water test no chloride, chlorine, low nitrate, nitride, and I water change before 3 to 4 days 30%. Now I will start in two days. Because my fish tank bowfin 120 gals, I think? , and I have eight fish'sIt does look like an injury. I’d try dabbing the area with methylene blue on a qtipand dose some triple sulfa just in case. Check that water quality.
