Albino Hymenochirus breeding

Hi!

I didn't even know that they are exist until I saw them in a local pet shop. Later I bought four young specimens and after a couple of months it turned out I've a male and three females (later I got 5 new, smaller frogs which aren't breeding yet). Since then they breed on every other week or so, I've hundreds and hundreds of eggs, however only a few tadpoles survive. I feed them with paramecium, later live artemia nauplii. The interesting part (at least for me) that tadpoles are usually dark grey, almost black colored when they hatch, and as they grow, their coloration fades away and they become visually albinos (or leucistic, I'm not sure). Here are some pictures of them.

Really amazing, congratulations!!
Were they more expensive or the sellers didn´t even know they are albino?
Continue showing us their progress.
Bye

Very interesting. Are the eyes red or dark?
I have the opposite going on here.
Different species of frog, but anyway, my albinos come from white eggs, and the normal and or splits, also come from white eggs, yet develop dark pigmentation over first week or so.
Have also had some yellow with black eyes, like tadpole above, but when they morph they regain normal green pigment.

Nice find what ever they are, thanks for sharing :D

Eze:
Shopkeepers knew what they are selling so albinos were a bit more expensive.

Green frog:
What you mentioned is strange too.
They have dark eyes at the moment, and most of the time the adults' eyes seem to be black too, however sometimes when you look at them from the right angle, they seem to be reddish, so along with the grey tadpole coloration that's why I couldn't clearly decide. I think it's safe to call them albino for now until we find out more about them.

I took some new photos about new eggs and tadpoles on the first 4 days, they definitely look grey here.

weird, something appears to be eliminating their pigment.

here's some of mine.

all eggs were white (this from breeding albino to an albino split)
pic 1, notice black dot (eye) on the one in the centre. that = not albino. will colour up to a normal looking tadpole. rest albino, notice it appears they have no eye.

few days after hatching the ones with black eyes start gaining normal colour/ albinos clearly different now..

There were many others, not just a few where I bought them, and looked all the same, just like selectively bred animals, so albino or not, I don't think it's just a random mutation. From what I can tell seeing their tadpoles so far, the offspring inherit the same fenotype.

I wish I were more into genetics. Sadly I usually forget most complicate stuff shortly after reading:) I found a dead tadpole (air-bubble in stomach), and while being quite large and developed, it was grey with black eyes unlike most of its siblings at this size. There are more, living ones with these features - I wonder if they become wild type frogs or will show different levels of hypomelanism.

Isn't this Hymenochirus color morph available in your country yet, guys? Does anybody know something about its origin?

Here's a new pic. I put them in a well cycled rodent cage base with lots of algae and stabile water chemistry, they seem to do well in it.

Here's a darker specimen I found, still grey while almost being a froglet. Definitely not an albino.

Allright, I finished rearing the offspring of my supposedly albino adults. The results are: no albino froglets, many hypomelanistic ones (which start with pure light color and gain more and bigger spots as they grow) and a few wild type specimens. Many tads and froglets died by some bacterial infection, but some enrofloxacin cured the survivors.

Beautiful. Looking at the first pictures, I was sure that they will be albino...

The tapwater here is quite hard and the pH is 8-8,5. My animals were kept at room temperature (22-29°C according to season and weather). 4 specimens in an approx. 130 l tank, with a 40cm water level. No other tankmates, lots of shady hiding places and caves (artifical rock background), only a few sphere moss as live plants in the water. Daily feeding with live tubifex, frozen artemia, bloodworm, shell etc. That's all I think.

Thanks for the information, do you know of any other breeders who have bred in soft water with a lower ph ? mine is typically 7.4-7.6. I have a group of eight adults 2.6.0, they are in an tank with a pair of breeding angel fish at the moment, though i am planning a species only tank in the near future and am looking for ways of getting them to breed. My males never call which makes me assume that something is just not triggering them to breed or something is amiss with my standard of care. They are in a three foot long 18" deep tank at 26c (78f), they are fed live/frozen bloodworm , live daphnia, occasional pieces of salmon or shrimp and any baby guppies they can catch, which is not many as my angels tend to get them first. Any advice you could give would be appreciated.

I'm not sure but I think the pH of yours must be allright. Some people say adding cooler water at waterchanges might trigger them to breed, just like feeding with live tubifex or chopped small earthworms (which definitely works in the case of many fish species).

Thanks , i will try that in a few weeks when i rearrange my tanks, if i am successful i will post about it.

    Do you guys think I could put some water ina clear tote and put my salamande rin to swim around? For enrichment and fun kinda deal? Do you think he would even like that? or would he sketch cuz its just water and the bottom is like 2 feet down kinda deal? Can they swim well? I dont want to drop him in and scare him unless I know for certainnheh can swim.I havent googled it yet. I know they go into vernal pools, but a vernal pool is a lot different than 2 to 3 feet of water straight down.

    Google says " Free-living adults rarely enter water other than for breeding, but a shallow, easily-exited water bowl will be utilized by captives. " is that true? So he would HATE dropping him in some nice deep water to swim around for a little bit?" Hes got a nice big tank to wander around in but I find he constantly wants to just chill under his big hidey rock, and peek out every once in a while Lol

    So, how often do I have to change the soil in my yellow spotteds terrarium? The soil looks fine, he stays under his rock all the time, so should I maybe only change put the soil from udner the rock? Or do I change it all out cuz its all stayed moist and I dont wnat it it mold kinda deal? Its been around 40 days with the same soil. It looks and smells completely fine though. I dont know what salamander poop even looks like, but Im not even finding any. I put pill bugs in his cage for him and they disappear, theyre not burrowing, so he MUST be eating them. What am I looking out for when the soil needs to be changed? Clearly the people whos aid they were coming to seize my salamander have forgotten and arent coming back.
