Ian (and others), I never caught anything that looked like C. aeneus in Venezuela. Just C. venezuelanus and C. venezuelanus "black." I also never saw them in the trade there either. In Colombia I have seen a C. aeneus like fish which is coming out of Leticia (Amazonas). Given the amount of...

Rusty,
Looks like the photos of Pseudocetopsis that I have, but it does not look like any of the spp. I have photos of. Great acquisition.

The key is to keep the sand substrate thin (about 1/2 inch or just over 1 cm). If you go very deep you can run into the anaerobic problem Rusty mentioned. That said,...

They need a few days to learn their boundries. It is a real shame to find your recently collected or purchased pleco on the...
