Is this what I think it is....TB?

My community tank has been going well since November, 15gallon tall. I’ve been very diligent with water changes and cleanings - my COVID hobby. I got paskai rainbows when it first cycled, as well as guppies, otocinclus, a betta and a GBR. All has been going well with no major issues other than a constant algae issue since it’s in a window (indirect sun) - I’m working on it. One of the paskai has the bent spine - see the photos, I put him in the cup just to get a good photo. It’s been like this for well over a month, possibly over 2-3 months - and I only just took the time to really look into it since he seems otherwise fine. No lesions, looks to have proper energy levels etc etc - just has a bent spine..... is it fish TB?
If it IS fish tb, and I need to euthanize - are the other fish in the tank ok since there aren’t any lesions yet or do I need to euthanize the whole tank?
Thanks in advance.

 

Croeso welcome to fishlore
I dont know much about the breeding cycle of yours but I know with my peacock cichlid you can get a few males around when fertilising takes place and have been told that is the end result with some of them, I actually got some at the moment, the same thing also happened with my danios and I always get a few bent spines

 

So... it could just be a sex injury? Here’s hoping.
I don’t think these guys have ever bred - certainly no fry that I’ve seen. My guppies have a few times, but you know.... guppies like to breed.

 

I'm sure someone else will come along with more information

 

I dont know much about fish TB but I would also think its more likely a congenital deformity as the fish itself and the others seem healthy otherwise.

 

I agree with TClare. It seems that a bent spline is a somewhat common congenital deformity, most likel do to over breeding.

 

Thanks guys - you have put my mind at ease. I just went to the LFS for some more nerites and showed them the photos - they were pretty confident it wasn’t Fish TB. Apparently there is a white film over the spine when it is TB. Much appreciated to all of you - the little guy is happily back with the herd, oblivious to this discussion and living his best life. The way it should be.
