Torn tail or fin rot?

[madmoz]

Noticed this today

This little fella lives in a 125 liter planted tank with four other orange venezuelan, five pandas, five gold lasers, 3 panda loaches and three otos.

Water parameters are 0 ammonia, 0 nitrites and about 5ppm nitrate.

He’s swimming and eating as usual and I don’t want to take him out unless 100% necessary.

Do I need to medicate the tank or just watch and see how things go?

Thanks!

It looks like he got bitten - odd with the tankmates. I would just watch it.

Assassin snails? Forgot to mention that there’s two in there to deal with a hitchhiking snail outbreak months ago.

Is there a possibility that some of your terracotta decorations could have some sharp edges .?.

Doesn't look like fin rot. Looks more like an injury.
