Can you identify this Hypoptopoma

I got 3 “giant Oto’s” a while back, they were all supposed to be Hypoptopoma thoracatum… however one is bigger, and shaped differently, does anyone have a guess on this 1st one???

The other 2 look alike, a little smaller, and a more pointed, higher bridged nose, and a narrower head, a little darker color…

I have only had two otos, affinis and cocama, and I had a jhrd time keeping them alive. The were my bugaboo fish. After having close to 50 - 60affinis die over time, I decided I should not try to keep them. Considering how many plecos I have kept this was a real surprise.

Plantetcatfish has a page with pics of most of the otocinclus and another for the Hypoptopoma. Here is the link for each maybe this can help as i cannot. You can click on any of the species below on the page and it will then take you to the profile info for that species. Even if there are no pics it still takes you to their page.

Can you identify this Hypoptopoma

His name is Fred and he's wanted by the FBI for scaring a certain fish forum moderator located in merry old England.

I’ve had one cocama for 2 years, but tried many others with no luck… now that I’ve gotten better at this, I have a handful more coming next week… going to try to get mine a couple buddies

 

[Colin_T]

you will be breeding fish next

 

[Magnum Man]

@Colin_T … are you saying you think it’s the sexual difference between the males and a female of the same species???
or were you referring to getting a handful of the zebra Oto's???

 

[Colin_T]

I'm not saying anything. Fred left a voice mail on my phone this morning after I posted and I ain't got nothing to say about him. I ain't talking to no one and I ain't going to the police. My lips are sealed and that's all I'm saying.




whispering, Fred is in with the mob and threatened to make me sleep with the fishes.

BTW... if you look at the 1st picture... "Fred" looks to have nostrils... they are harder to see with the picture quality of the 2nd picture, but pretty sure the other 2 have them as well... pretty sure it's not "hole in the head" but, I've only had him for a month, so??? if they aren't Nostrils... what would they be???

 

[Magnum Man]

In this older picture, the bigger one in the 1 picture of this thread, is in the background, one of the others on the stick… it appears to have “nostrils” also???

A little blip off the www.

"do fish have nostrils? While fish do have nasal openings called nares, they are not used for breathing. Instead, these nares, similar to nostrils, serve the purpose of smelling their underwater environment."

My otos definitely have clearly visible nostrils.
