Neither had I until I went in recently. It's EXACTLY the same.

Proper old-school style shop, but still got some tasty fish, especially in the nano tanks. !

Re: L002 breeding project - Trapping after 3 days?!

They decided to do it in an floating oak cave that wasn't waterlogged yet instead of the many more suitable options on the tank floor
For what it's worth, in nature, the wood-dwelling loricariids such as Panaqolus and Ancistrus are more than happy to cave in floating logs.

Re: Adding fish to my aquarium, need help to choose!

I was told the thing is Apistogramma in the Amazon area live in small creeks, under the trees. That is, they never see sun, and therefore the water never gets to 30 C A mile away the situation can be quite different, no trees, lots of sun - and no Apistogramma There are always exceptions of course,...

@racoll, do you expect your Negro fish are the same? Or slightly different (you mentioned the presence/absence of the black seam on dorsal fin of Negro fish)?

Re: Can you ID this Hypancistrus from the Orinoco region?

You can find somewhat zombies in the lower Rio Negro (some somewhat spotty), so it would not surprise me that there's a similar fish in the Orinoco system. But that area is pretty well explored ... where exactly is Patacame?

Re: Microcambevinae, new subfamily in Trichomycteridae

Making phylogenetic assumptions based on a small amount of data can likewise be very misleading. With a small amount of data those incorrect relationships tend not to be well supported, and so the gut feeling is that with more data they will be resolved. They often are resolved with 100% support .....
