Hm i don't think it is a swimbladder problem, the swimming looks relatively normal in the videos.
no they are making it difficult to see whats wrong apart from what i said before about the whitening around some of their fins and a few 'wobbleing when swimming' and a few staying at the surface more than normal but the gills look fine, no signs of redness or inflamation but i will keep this updated if there is any developments and the spare filter is now in aswell, cheers for your help.
