White tips on harlequin

[Sophiel]

Hello,

Just been looking at my fish and noticed this harlequin has white tips on its tail? Is this normal?

It looks like the tail has been bitten. Regular water changes should take care of it (30% weekly, as always), but who are the tankmates, and how long has it been at your place?

I have 4 harlequins, cherry shrimp, wood shrimp and 2 nerite snails

And did you just get the harlequins? That looks like a pet shop style injury.

No I’ve had them for about 4 weeks now, and I’ve only noticed it today

Hobbyists get alarmed about "fin rot", but most of the time clean water solves issues that look like that. 4 weeks is still the quarantine period for new fish, but there, I suspect she's been nipped by another harlequin, maybe a male (she's a she). 30% water changes every week (forever) and keep an eye on it. It should clear in a week or two.
