Pebas Complex ID - Roca Eterna?

[Ekona]

Just received this male and female (pics below) from Scott at Amazon Tropicals labeled as "A. sp. purple." These are really pretty fish and came in in excellent condition.
They male looks very much like A. sp. morado as pictured in Datz (A88), and even more so like the male A. sp. Roca Eterna pictured in Tom C.'s website. What catches my attention are the saddle-like bars on the dorsum of both the male and female. They are similar to the 'inverted T-bone steak' blotches on the fry of the Roca Etrna, also on Tom's website. Are those bars characteristic of Roca Eterna, or do they also occur in other pebas sub-complex species?

My apologies for the out of focus photos, but I post them in the hope there is enough detail to picture the oddly shaped dorsal bars. If clearer photos are needed for positive ID, I will try again tomorrow.

Male

Female

Also, I've not kept pebas sub-complex species before, so any husbandry tips welcomed. For instance what sized aquarium is generally recommended for keeping/breeding a pair? Water parameters?

Thanks,
Dave

Can you send in-focus photos and photos of the female?

 

[Ekona]

I will try to send photos with better focus - I realize the ones sent were basically useless for anything but showing the general pattern of the dorsal markings.

I take it from your question that fish in the second photo is not a female, in which case, I cannot send a photo of the female - as that fish was sent as the female of a pair.

The bottom photo is so out of focus that it's impossible to say anything. I guess it might be a female.

I will try to send an in-focus photo of the female... as I think that's what it is, but can't say for sure, as I've never kept these before.
