Blind cave fish

[emeraldking]

I've got blind cave fish in one of my paludariums. Despite of the fact that they are more carnivores, they won't grab guppy fry (they share the same water). But some greens will be grabbed as well to eat.
Took some out of the paludarium to give you a closer look at them.

They're also called mexican tetra.

These always remind me of my parents tanks from when I was a kid (back in the '80s). Back in the days of bright coloured gravel and undergravel filters being the height of filtration technology. I always remember being fascinated by these guys.
