Neon tetra is pale and getting nubby tail fin

Anyone know what may be going on with this fish? You can sort of see a healthier looking tetra for comparison. I saw it eating and schoaling with the other tetras, albeit sticking closer to the decorations than the others. I see no other issues in its behavior. When I grabbed the test strips, they appear to be old, so please bear with me as they are likely inaccurate. The parameters are:

* 80°F

* 75-100 GH

* No chlorine

* 40‐80 KH

* 6.7-7.2 PH

* I have no readings on ammonia, nitrite, or nitrate. I am certain the first two aren't present with all the algae and plant growth I've seen since this tank started getting more attention again.

Now, all these fish were recently (2-3 months ago) purchased from Petco and dropped right into the tank without quarantining.

 

What are your thoughts?

Could be fin rot what I would do is get  ammonia nitrite nitrate liquid test kit or strips just in case something off with your water parameters and I would do a course of kanaplex or maracyn2 as most case of fin rot are caused by gram negative bacteria @Red Rainbowfish

Two of my tetras had a tail like that once. I treated them for fin rot and it eventually grew back, took sometime though. I’m not sure about the pale colour though.
