Hi all,
I picked up these at the Catfish Cataclysm rare catfish auction. They were labeled as Hypoptopoma sp. Rio Tigre so I'm assuming Peru as collection point. They look very similar to

Hi gulogulo,

Does your fish have the distinctive black stripe (seen in H. guianense) through the middle of the caudal fin, dividing the fin into approximately equal upper and lower lobes?

Great find
They certainly resemble my H. cf. guianense, which were also imported from Peru. I agree with Eric, a better photo of the caudal fin would help to confirm their identity.
Mine have proven to be excellent algae eaters and I haven't lost any over the two years I've had them, so in my experience they're more robust than Otocinclus.
They grow to about 70mm and also enjoy eating red bell pepper, spinach, and courgette/zucchini.

I will check the caudal fin and try to get some additional pics.

Here's a quick snap of two of mine, making fancy shapes out of a home-grown yellow courgette. They love their fresh organic veggies.
Forgive the photo-bombing Brachyrhamdia...
