What happened to my betta's tail?

[KhloeM]

hi everyone! so i recently moved both of my bettas into new (cycled and tested with API Freshwater Master Test Kit) 5 gallon tanks! they looove all of the extra space! however, today i noticed that Zeus's tail is torn! i don't know what caused it, if it was the filter or a decoration, but i will post a bunch of pictures of his tail before and after.
here's a picture of my tank (currently. i will be adding live plants in a little bit) so you can get an idea of what's in it: not sure if it was the temple decoration, but i checked it out for sharp edges and it felt smooth. it could be the plants in back, which i could definitely ditch, but i'm reluctant to get rid of the rest (but if i have to, i definitely will!)
here are pics of Zeus's tail before the upgrade:
and here are pics of his tail currently: in this one, focus on the very tip. you can see a piece of it hanging off basically, and you can clearly see how it is like split or somehing (at the very end in his tail)

sorry, the rest wouldn't upload:
as you can see, there is a kind of "slit/split" in his tail in the back, and a piece of it handing off at the end. also, his bottom fin is, like, twisted or something at the bottom. please help me with this if you've ever experienced this before. thanks!

If those plants are plastic, that's what most likely caused it.

i feel like it's the green ones in back. they aren't jagged, but he's been going in and out all day. and the bamboo thing is not sharp it's soft, and the tree has rounded leaves... i'm just going to take out those plants right now. would you say his tail is pretty bad or no? i've never had this happen before so i don't know if there's anything to do about it? thanks!

Just as long as it's not bothering him, I think it's not too bad.

okay, thanks! yea it definitely doesn't seem to bother him, he's swimming happily like normal!

UPDATE: now i'm debating if it's actually fin rot... i can't really tell! if i put aquarium salt in and it wasn't fin rot, would that harm him?

Mine goes through all my decor and plants fake and real. Some of his fins get nicked a little bit. Unless it's getting bad I personally wouldn't worry about it.

thanks! i just feel like it's pretty bad because it's like ripped and torn up would salt harm him if i put it in but it wasn't fin rot?

No bettas are not sensitive to salt that I'm aware of. Salt baths are commonly used to reduce stress.
