Cory With A Split Fin

[idlefingers]

I just noticed one of my bronze corys has a split fin. It doesn't look chewed or anything and he seems fine - sifting through the sand looking for food. I haven't fed them yet since noticing it, but I'm confident he'll eat as he seems fine.

I dont have any agressive fish and haven't noticed any bullying, added with the fact it looks very clean and not bitten I'm baffled as to what's happened.

Is there anything I can do (medications, etc) to help?

Here's some info about the tank:

200L / 52g over-filtered, well-planted tank with 4 pearl gourami, 15 neon tetra, 2 bristlenose plecs, 1 king tiger plec and 6 corys (including the injured one)

PH: 7
Ammonia: 0
Nitrite: 0
Nitrate: 10

10% water change weekly (twice weekly sometimes) done yesterday. Treated tank with flubenol 15 about 2 weeks ago as I saw one of the corys flicking (not this one).

Thanks for any advice!

Split fins mend on there own in good water quality.
Good luck.
Just because a cory flicked once I wouldnt of gone in with a med so soon.

Okay, thanks.

i didn't dose the fubenol straight away after seeing the flicking, it had been doing it a good few times over a couple of days before I decided to get some. I thought treating early would be good?

Yes if you know what you are treating for.
Corys do flick from time to time.
