Hypostomus cochliodon is one of the more interesting plecos that I have kept as it is a diurnal wood eater. My fish is currently around 128 mm SL (170 mm TL) as measured today. I’ve been meaning to measure it for a while as it would be interesting to know if it ever reaches the 230 mm as reported by Webber (2003), or remains at the 7 inch mark, as the original paratypes mentioned by Kner. The fish feeds well on courgette and wood, but takes no interest in dry pellets.
I was quite surprised that the fish had no Wikipedia article… it has one now!
