I have produced a few dozen blue jeans over the past few years, from a wc pr that is now 10+ years old, these were some of the first darts i owned. this wc pr has been in the same tank for the whole time, and is a simple 30 gallon with a few plants and film canisters at varying angles jammed into the substrate. i have not moved them for fear of upsetting them. i have found them to be extremely male heavy in terms of the offspring they throw, which may explain why you dont see many for sale, or why people hold back so many, trying to get females, at least thats my reason for doing so.
i also cannot get my F1 to raise or even deposit tads, which is incredibly frustrating. I think as a whole the blue jeans are a slightly different beast that the other pumilio, or a little more picky in their requirements. Whether its dietary, environmental or other, Id say at least as far as mine go, that im missing something. im also get only about a 50% surval rate of froglets, they all seem to morph out looking great, but some dont ever grow, while others grow like weeds, all raised identically. I rarely lose a froglet from my other pumilios.
I do think the blue jeans like it wetter than other pumilio, or thats what i found to be the trigger, i keep the substate really wet and soggy so that little puddles are always in the depressions of the soil.
I think Brent, as usual, is on the ball with the large tank, i think that's probably the way to go about breeding them with the best chance of success, as you have the room to provide ample, and variable deposition sites then thats a big step in the right direction, and generally i think it gives them a better feeling of security which is important. Im really surprised Rob that you have bred them in a 8 gallon, and im really surprised that mine breed in the tank they are in.
And Brent as for setups that did not produce froglets, you name it, i have probably tried it it with F1 blue jeans, from 10 gallons to 60 gallons, with and without broms, with, without film canisters, with film canisters and broms, really wet, dryish, with an extra male, extra female, just a pr, leaf litter, mud bottom., almost exact mimics of the 30 gallon that is producing, nothing, a few good eggs here and there, but the females never show any interest in depositing them.
