White Cloud missing a tail!!!

[vantgE]

Their is a whitecloud in my ten gallon missing a tail, right now it can barely swim, by tail i mean non of that feathery stuff and probaly a bit of mit too, he's floating at the top al,ive but i've isolated him from the other fishes, however i think we should just euthanize it if it's not going to grow the fin back anyways as the other clouds were trying to eat him and it'[s kindof helpless any thoughts?

And entirely unrealted question but why are their white flies in my goldfish tank on the lid?

Awww poor fishy. If he looks really bad and when i meen bad i meen REALLLY BAD , I found out a way to untinize fishes humanily, stick him in a solution of 90% water (clorinated) and 10% vodka. And believe me...he will be one HAPPY fish when he passes!

But give him some time before you deside to do it (if he wont grow his tail back for some odd reason. his tail will grow back though!)

DO NOT EUTHINISE!

the tail will grow back, given time.
The key is good quality water, daily water changes and melafix.
