My betta's bottom lip is funky. Ive googled everything and I can't seem to find anything similar to what it looks like. It's not cottony, or white... but is bumpy and recently looks scabby? or dry? His bottom lip protrudes further out than most bettas, and doesn't have a normal lower lip shape. There is also black marks on it and he's been eating less too. Has anyone seen or had this on their fish before? Any help would be great.

A few days ago I tested my GH because Spritz seemed "off" and way lying on the bottom of the tank quite a bit, and it was at 21 drops!!!! Since then Ive been doing water changes daily and gravel vacuuming to try and get everything neat and tidy. I don't know if these 30 pond snails are causing the GH to spike, but it's the only thing I can think of. Since starting water changes its down to 11 drops as of today, which is still high. Spritz has perked up since the water changes started.

PH 6.5 (My tap is 7.0)
Ammonia 0
Nitrite 0
Nitrate 5

GH 200 (My tap water is 50)

I’m unsure of the problem, but I really hope that this thread gets seen by someone who can help you. Best wishes to you and your fish.

I had a very similar thing happen to my own betta's lip. I still have no idea what caused it unfortunately but my assumption at the time was that he somehow had injured it. I treated it the way I treat any wound and it has since gone away.

The way I treat injuries is by increasing water changes and treating for any fungal or bacterial issues. I also do aquarium salt baths once a day for 4-5 days. You don't have to do that but I find it helps. If you choose to do that to your own betta make sure that if he shows signs of stress you return him to his tank and don't do more.

Also make sure anything you decide to use is safe for snails

I treated with Paraguard and he did a quick 180. I also got a separate container for my 50 pond snails. I have some meds coming that Were recommended by ACoop, I’m gonna give him these meds in their recommended dosage for new fish just to make sure he didn’t have something underlying.

The Paraguard Also didn’t seem to affect my Mystery Snail at all this time. I’m just rambling in case this ever happens to someone else And they need info.
