Hi
I added 5 new guppies to my established tank a couple of weeks ago- the problem lies with just one of them. 4 of them are males for definate as they have gorgeous big colourfull fins but the 5th has a pointy tale and no top fin. It just looks weird, kind of deformed.
It has been struggling today so I think it has been picked on? It is now in a floating tank inside the big tank as it is on its side/upside down


.
I dont think I can save the poor fish but does anyone know of anything I can do.
