I've never had a half moon betta before, and I've had this one for a few months, his name is sparta (rightly so), and I really could use some help figuring out if he has fin rot, or if he's attacking his tail, or if the plants are shredding his tail...we noticed his fins start to become very jagged, and today i noticed a bottom piece of it that looked kind of bloody. I'm going to attach some pictures, I'm sorry they are kind of blurry, he won't sit still! He's eating just fine for the time being...

Hi Lara, you mentioned the edges of his fins and tail look bloody? I'd say you have a fin biter, who's tail and find may be infected, or at least irritated.

The good news is its treatable, at least the rot. Clean water is his best bet. Normally daily water changes are required. You shouldn't need medication. However, I did notice you mention adding salt. Aquarium salt should only be used while treating a fish, and even then, at a dosage of 1 - 3 tsp a gal. In your case 1 trap a gal should be sufficient to start.

I would also ask, is that grass plant plastic? The leaves look rather spikey. They may be tearing his fins as well.

He is pretty aggressive...The plants are all plastic and kind of spikey, we will replace them with silk ASAP. Thank you very much for your reply!

that's tail biting. :V it's a difficult fix for some. i find it easy to stop.

do 3 water changes a week to stop the infection. at every water change, rearrange where his plants and other decor are located. that'll keep him busy exploring, and stop the tail biting. that's what i'm doing with my HMDT, who's previous owner really couldn't stop his tail biting(he came to me with almost a stump of a tail. :B it's now growing back beautifully~!).
