O. pumilio "Rios" morphs - hard to get ?
#1
I've been getting a lot of questions and comments on the two "Rio" morphs - Rio Guarumo and Rio Branco.

First. "Rio" means River in Spanish.Guarumo and Branco are locales, near where they are collected, supposedly. Guarumo is often seen spelled "Guarmo" as well.

Guarumos are mostly yellow / greenish and seem to be able to change colour from light to dark, much more than other pum morphs - green to yellow.

Brancos have a more tan / reddish colour, but are similarly patterned.

I think, of all the imports that I've ever seen...the 2 Rios seem to be the least commonly included in recent importation years.

I currently have 2 groups of Guarumos - 1.2 and 1.1 They both breed and produce froglets but out of 10-12 that have morphed out, only the 1.1 group has just recently produced 2 froglets that seem to be just on the cusp of reaching juvenile stage. I have talked with 3-4 other breeders, some as far away as CA, and all of them agree that this morph is one of the most challenging in terms of getting a froglet to adult age. 75% of my froglets that perished either had SLS or simply "wasted" away, getting thinner and not actively hunting ect. Fecals for adults came back negative.

I don't know of more than 3-4 people even keeping them in viable groups and adults or even froglets are rarely ever offered - never in my eyes, actually.

Some observations....

Phil, I'm curious have you are anyone you spoken to using clay in any of your Rio tanks? I'm far from an expert but from the research I've been doing it sounds like the clay substrate may be help in providing calcium to the froglets.

Mike,

I don't have any clay tanks, yet. I have some ABG tanks and even some organic backgrounds with florite ect to help with extra calcium. I strongly believe that "clay" is the new wave of substrates. That said, I do get numerous other pumilio to morph out fine - Eldorados, Caucheros, Man creek ect. It's only a problem with the Rio Guarumos.

The Rio's are way up at the top of the want list but I've never seen any available.

Out of my 2 breeding groups of these: 1.2 and 1.1.....

and over three years.....

I THINK I may have 1-2 progeny, FINALLY. Left them in the parental vivs, even now. I can only guess how old they/it is. @ 6-8 months, maybe ?
