Guppy Nipping Platies

You don't happen to have a fry net/box on hand do you?

Or an empty margarine/ice cream tub complete with lid? If you do, punch some holes in it smaller than a tiny guppy and secure it somehow to the side of the tank. Bits of wire, length of string, whatever you can find that would do the job. Punch holes in the lid as well and put that over the tub. Guppies can jump. If you have any plant bits, real or fake, it would stop the guppy getting too stressed.

 If the sides of the tank are mirrored, the platies think there's more tank through the mirror. They'll eventually learn they can't get to it.

I've heard of some guppies being nippy fish. Once they've gone, any damage to the platies should heal.

Yes and the unfathomable thing is, she spent nearly two months going mad like me doing a "fishless cycle" ah well, iv'e got them for now, things seem to have calmed down, ive bought a little islolation box just incase he has to go in the naughty corner lol. i'll see how he carries on and he may go back to shop next week if he plays up, (he also spoils my colour co ordination plan)  Update, guppy seems to have calmed down a bit, and is quite friendly, wonder if he's trying to mate? anyway what i'm wondering now, is it unfair to keep one of a species, as i now have one tiny endler, i'd be happy to keep him,  and one small fancy guppy, who is a bit too garish and frantic for me,  should they really be with lots of their own kind, if so, i really don't want more so will have to see what shop policy is on returning.

Endlers to tend to be less annoying to tankmates than guppies. I have males and they spend almost all their time together, either displaying to each other or chasing each other, but without harming each other. You could always ask the shop if they'd part-ex the guppy for endlers.

If you do get more male endlers, they will display to each other. They spread their fins, arch their bodied sideways and sort of twitch. It looks quite alarming the first time you see it. 

good for you rescuing the guppies

It certainly had me wondering what was going on, it is funny to watch though
