Greetings. Just picked up a group of these and have more, on the way. They top out at 1.5". Cheers. - Frank

Hi Frank,

I saw this little Nannoptopoma for sale here in Singapore, but I avoided them, since I felt these small critters were very sensitive species.

I kept this other tiny "oto" some years ago, sold under the trade name of "Tiger Oto" in Singapore:

Hi Benny. That is an awesome looking species. I will be keeping a close eye on the export list for some of those. Thanks for sharing. Cheers. - Frank

Hi Frank, I'm not Benny. You can call me Jianyang. Benny took the best photo of this species, at least in my opinion.

Yeah that little fella was an awesome species. It was very fragile though. Did not survive longer than O. cocama before people found out Zebra Otos were more herbivorous than omnivorous. I believe it requires a specific type of food item to survive. No idea on their habitat because this was from a commercial import some years back. You might want to source with Peruvian exporters for this little fish.

They were no bigger than an inch for the largest specimens, rest were much smaller and patterns were non identical I believe.

Hi Jianyang. My apologies. I was not paying close attention.

Yes. Very, very well done.

I am always searching each list for unusual cats, of any kind.

Let's hope that we come across them again, one day soon. Cheers. - Frank

Guys, I'm also maintaining a small group of Nannoptopoma sp. Peru (aka Orange Oto) and doing well on blanched zucchini, peas and tubifex. In a way, I'm regretting not putting aside a group of Parotocinclus sp. Peru (aka Tiger Oto) when I had access to them. Both of them can be sensitive but it gets easier if kept cool or sub-26ºC.

A late welcome to you, Frank, and thanks for sharing your experience in AQ.

Corydoras species is not my forte but they're interesting enough for me to want breed them. I've done a few but not quite as many as you and Kim... but I'll try to catch up!

I'll be all ears when the Nannos spawn for you.

Hi Ron. Thank you and it's nice to make your acquaintance.

They are truly my first love. They're not that hard. Like most things, it takes patience more than anything. I've only been at them a little over 10 years and have spawned 65 species.

I'll be all ears when the Nannos spawn for you.

I'll be hoping, but NOT holding my breath. lol. Cheers. - Frank

Have you found any signs of sexual dimorphism in your Nannoptopoma Frank?

Hi. Up until now I have hardly seen them at all as they stay in the leaf litter. When one surfaces, I snap a pic. I have seen one that looks like it would probably be a female for certain. Considerably larger than the others and quite plump. :-) Cheers. Frank

At least some progress.

Perhaps they can be sexed by the shape of genital papilla like some other loricariids.

That type of expertise exceeds my pay grade. I'm a Cory guy. lol. - Frank

So... besides being larger and pot bellied, would you say that the shape of head (top view) has any difference in sexual dimorphism?

My little group of 5 are reclusive most of the time, like yours, preferring to forage amongst leaf litter or resting beneath driftwoods. Once accustomed to their environment, the orange color on their foreheads takes a deep tone while dark bandings are almost black. Well behaved fellas and definitely not to be kept with gregarious tank-mates. Mine are all about the same size, width and colors, which lead me to suspect I have an all-boys team.

Oh well... I won't be holding my breath either!!
