I have a Lepor sf Galaxias (L240) - its a stunning fish and yours is definately not that. While looking for a mate for it I got (through postage, hadn't seen the fish) two different fish - both as L007. Their colouration is different (one is more yellowish than the other) and the shape of their nose is very different (one is way longer and more pointed than the other). Having said that, the L007 is considered by some to be the same fish as the L29 (my supplier thinks one is the male and the other the female version of the same fish). I cannot comment on that as they haven't spawned yet, the younger is too young. I also have one that arrived from a new brazilian supplier (I was rather active looking for a mate for my L240

) - it was classified as Lepor Galaxias Blue Star - and that is a different fish too

All the fish that came as a Galaxias though have one thing in common - and that is they are quite "private" individuals and not the kind of fish you will see strolling about in the tank.
My experience with Hypancistrus is quite different - behaviourwise.
What I can confirm hand in heart is that the various Galaxias species I have (and I think I must be covering the range!!!

) don't look anything like Hypancistrus in shape - for starters the head is different. Thats why I asked if you could take a dorsal view pic of the fish ...
I still think its teeth would point us to the right direction - check the Aqualog for the teeth of L201.
PS I am expecting two new tanks in the next two weeks - if that hasn't been resolved by then I will take some pics as I take them out to re-house them and post them here for you to see
