Water Parameter?

So I have a ten gallon live planted tank with a male betta, who has been loosing his fins and not because of fin rot, 2 corydaoras, and 2 harlequin rasboras.
Here are my water parameters:
Ammonia 0
Nitrate 19
Nitrite between .7 and 1
hardness 150 (normal I live in fl)
chlorine 0
Alkalinity 130
pH 7.5
I'm fairly new to knowing fish, so is this normal? Could the parameters be the cause of my betta "fin biting"?
Thank You In Advance!

 

Those parameters are not normal. In a cycled tank there should never be any nitrite. I'd also do a water change to get those nitrates down.

Have you actually seen the betta biting it's fins?
Why do you think it is not finrot?
You have some stocking issues that could be contributing to the fun problem

 

I agree with BottomDweller. I also recommend getting rid of your 5 in 1 test strips, replace them with the much-more-accurate-API-test-kits.

See the odd thing is I just did a 50% water change yesterday. Which is why I don't get why the nitite and nitrate is high. I believe its fin biting bc i've tried multiple treatments for fin rot and it doesn't seem to be getting worse. I've seen him bit is fin once but it has stopped.

 

The best treatment for finrot is very clean water. Generally I'd recommend 50-70% water changes every other day or daily.

If he is biting his own fins it could be due to stress (maybe the other fish?) Or boredom but I don't think that is very likely in a 10 gallon.

I would watch out for nipping from the harlequins. They are not nippy fish but since there are only 2 of them and they are schooling fish they might nip.

The nitrate and nitrite are odd, especially if you have just done a water change. I would test your tap water to see if it has any nitrite or nitrate.

Well water has 0 nitrite and 5 nitrate

The reason the harlequin’s are in a small school is because none of my fish stores has them in stock and online the shipping is way to much. My local Petsmart said they will have them in two weeks. They kind of all just mind their own business in the tank. Also I did the water changes with him for a month and so no improvement and I tried medication and saw no improvement
