As for my fish....I have had posts from cattleya and the general opinion was L399. That web page is a bit mixed up for me to tell the L400 from the L399, but from the shots taken above the fish pics, I would say L399. Now my fish have setteld there colour has gone amazingly white and black, such a nice fish
While I have all your attention

Anybody know the physical differences between L066 and L333, and also the L400 and L399 Variants? Im a bit new to Hypancistrus and would love to know if there is a simple

rule of thumb to guide me in the general direction
Edit: Did this to help me compare the two fish, Might wana put it on your desk top to see it in full, I thoght it would help me sex them, see the difference in the nose?

hmm somthing witty....
