Thanks guys for the feedback. I have looked at the pics for columbian cats and I don't think it is one of those, it was sold to me as a member of the synodontis family. The Bala shark pics that I have seen and the columbian pics those fish don't have and spots or they have very little. I know the pic of my fish isn't the best but they are very hard to photograph as they never stay still longer than 2 seconds.
