Cobra guppies losing colour

[wilmo]

Hey folks
My cobra guppy is acting strange sitting at the bottom of the tank all the time and now the base of it's tail is like losing it's colour and going a bluey colour. Would post a pic but can't get one close enough to see it. Plus I've added aquarium salt and cranked up the temp to 80F already because I'm treating my Betta for clamped fins
Cheers

80* is what the betta should be at anyway, or you risk fin rot all the time.
Are you sure the betta is not biting the guppy?

100% sure he's not. Never seen him go for anyone. He's the kinda fish that likes getting his belly rubbed and comes out to say hello wen u turn the lights on. Lol

Well, clean water is best, so if you can do more water changes for a while that might clear it up. Make sure you keep your eye on it for a secondary fungal infection though.
