Help me ID mystery Parotocinclus (solved)

Post by SammySam »

I bought a Parotocinclus maculicauda and Parotocinclus haroldoi batch and these two contaminants arrived! They're so pretty but I have no idea what are their names!

#1 (IDed as Hisonotus notatus)
Image
Dark body, very faint red in its fins. 2"

#2 (IDed as Schizolecis guentheri)
Image
Very light with greyish brown stripes on its head, and common pattern along it's tail (compare with Parotocinclus #1). 1.5" - 2"

Parotocinclus maculicauda
Image
The "type" of P. maculicauda of my batch. Leopard-like markings and intense red on the fins and snout. There are no relevant sexual dysmorphism regarding coloration in most Parotocinclus populations so I believe #1 and #2 are either variations or completely different species. 2.2"

Parotocinclus haroldoi
Image
Nothing like the others. 1.5"

First off, it's not likely to be a Parotocinclus because there is no adipose fin. Have a look a Hisonotus or Pseudotothyris perhaps? Hard to say exactly from your pics, but the caudal fin pattern might best help with ID.

Thank a lot for your response! That's true, I have no idea how I didn't notice that detail.
I believe #1 might be a Hisonotus notatus (notice the tail of the little guy in the back of the picture), but I still had no luck finding #2.

That's a good call. I'd guess #2 might be the same species and looks different as stressed or on pale gravel. Are they in the same tank, for how long please?

They have been in the tank for a day now, and they took an hour or two to colour up well. There is no noticeable change in the base color of #2 when it attaches to driftwood or other dark surfaces, except for the greyish markings, which turn darker.

They have been as active as your usual Parotocinclus since they settled down.

I'll be looking through Hypoptopomatinae and see if I find anything similar.

I don't know if this makes sense but #2 also has really small pupils/eyes. I'm not sure if it's a trick of the light since it has white eyes, but it's the first thing I noticed when I saw it.

In that case, it's maybe Schizolecis guentheri?

Glad to help, they are all brilliant fishes and all most definitely "spawnable". Enjoy!
