Thanks Jools!!

Female

Guess I'll never know what they are.

Pics of unknown Sturisomatichthys species (44 days old) with Farlowella vittata fry (48 days old(.

1 was staying curled and died at about 17 hours post-hatching. No losses since.

Over 4x the size since hatching.

Had a pair. Then 12 fry.

Now 36 eggs laid last night.

Likely not Sturisomatichthys panamense per Jools information in the above post.

Same thing as when I raise Farlowella vittata fry: Bacter AE and Spirulina powder, Nori sheets, zucchini, and stones and driftwood chunks with algae anf biofilm growing on it.

Two becomes 14. FISH-MATH.

Does anyone know where I could find reference material to determine species? I doubt they are the critically endangered fish as sold.

Close to hatching I think!

Sturisomatichthys panamense perhaps? Hrmmmm...

Looks like eggs are fertile woot!

Thanks @bekateen - much appreciated. Every clue helps!

Been breeding and raising Farlowella vittata for a few years so hoping can raise these.

I love to see a species reproduce in captivity; to me ir means I am providing a good environment for them.

Five more pics. ALL are of the male except the full-body view (last one in prior post) which is the female.

I'm no photography expert by any stretch. Here are the best of what I could gather.

For future pics, I have cleaned the aquarium glass with alcohol.

To my surprise, I now see 12 eggs the male is guarding. Tankmates are South American tetras.

As for collection location, it is unknown. Five of ...

I have a pair of catfish I would like to know what species they are.

They were labeled as Sturisoma panamense, but am reading they are rarely if ever imported to US.

What photos are needed to narrow the species down?

Thanks!
