Hello,

SO, I did not know that the eggs in the tank were a hybrid cross but it turns out they are "Agrejas". I am attaching pictures of what the first batch of froglets look like. I have no idea what I did wrong but please let me know since I have many more eggs incubating now and some tads. Thanks for any posts! ericR

here is a different frog:

as some were tads:

All of the tads that you have photographed exhibit SLS. There is no definitive answer to what causes this, whether it is genetic, the nutritional supplements the parents are getting, what the tadpoles are eating, the water they are raised in, the temp of the water, and many more other variables. If this is happening to the majority or all of your tads, it might be better to just destroy the eggs as you dont know if they are hybrids.

I missed something along the way, perhaps, but just what are "agrejas?" Where did you get the eggs in the first place?

I tried to do a search on "agrejas" and got into some Portuguese porn sites.

Those are cool looking frogs, but it would be nice to have a complete history on them before making any comments.

Hi,

I was told that Agrejas referred to the hybrid cross between D. azureus X D. tinctorius. I have a large planted tank with mixed species of frogs. There is a pair of D. auratus and other individual frogs. I started getting eggs so assumed that I had a breeding pair of D. auratus but you can see from the pictures, they are now auratus. I have no idea they would hybridize.

My main question is: Do you think the froglets are mutants because of the genes from being hybrids, or is it a problem with my husbandry of the tadpoles?

Thanks for your time, ericR

I don't think you can call them "mutants," as this is a term for a spontaneous change in genetic material, such as the chromosomes or codons that make up the genes, and not due to hybridization.

I'm not certain that they do have spindly leg syndrome, (SLS)although my experience with this is limited to just a single occasion in a pumilio, where the front legs failed to emerge at all. (Subsequent froglets were normal.) These front legs do appear to be a bit "spindly," however, not very well coordinated in the same direction, and one of them appears to be missing a front leg entirely. They do look more like auratus than either tinctorius or azureus, but you may certainly get hybrids in a mixture of the these three species, and what they would look like is impossible to predict. If you are going to keep them together, I would pull and destroy all eggs, as suggested. If you want to breed, separate your known auratus pair and breed them, or any other known pairs of the same species. The tinctorius and azureus are essentially the same species--some people consider azureus to be a morph of tinctorius.

It's your own business if you want to raise and keep hybrids, but don't sell, give them away or allow them into the market in any way, as the ethical trend is to keep the species and morphs within the species as close to the originals as possible.

If you look on the frognet archives, you will find extensive discussions on SLS--no absolute conclusions, but it's an interesting read, especially since it has been suggested that your tadpoles have this.

Oops, I forgot to put in the picture of my D. pumilio bastimentos baby with SLS. You will notice that he has no observable front legs what-so-ever. On necropsy, they were barely budding.
