Hypancistrus sp., L-201. Ingo Seidel looked at these while he was visiting my house and said they are not H. contradens or H. inspector, but are L201 that do not have a species name yet. These are from the upper Rio Orinoco and Negro. Just like the zebra plecos, these are meat eaters, not algae eaters. Keep these at 80-84°F. Mine are breeding constantly. I have two pairs of these so I always send offspring from both pairs (for example, if you order 6, I send three from each pair). As with everything on my site, they were born and raised in my own home.
