Thanks John. I absolutely must agree, they are wonder-full
No, i didn't breed these youngsters myself, but got them from a German breeder to start another breeding-group. They're about 3 months old now, eating like tigers and growing fast.
Andrew, i wasn't very lucky with the (wildcaught)
adults, lost 3 out of 5, all females. Hopefully females are the majority in the captive bred group i'm raising now.
(Sorry John, i caused you some trouble by mis-posting these pics).
Sorry to hear you didn't have any luck with your adults. Can you see much difference between the 2 original adults you have and these juveniles as to if the parents of the juveniles came from the same location?
The 2 original adult males are wild-caught specimens with dorsal shades of green and a ventral deep orange. The juveniles aren't old enough yet to show their definitive dorsal colouration. Ventral colouration by using a colour-enhancer for birds on their food.
The juveniles are F2 so i have no idea where their Chinese ancestors once came from, but the natural habitat of Bombina maxima is almost entirely located in the Yunnan-region.
In raising my Bombina variegata kolombatavici the colour changes with age.
At metamorphosis froglets are a drab brown, after a month or so they turn green, then as they age this green turns darker until it becomes a bluish-grey at about 2 years.
The ventral coloration also changes with age, at metamorphosis the ventral surface is a light yellow almost white, over a month or 2 this turns to a pastel yellow and hints of light blue appear, then as they age the yellow gets deeper and the blue disappears.
With B.maxima I believe the froglets start a light reddish brown, this will change overtime to greenish gray and may even develop a golden tint. Also the ventral surface of most CB maxima I have seen are a light yellow but as Han pointed out the juveniles in the photographs have been colour fed.
I'm experimenting with colour feeding B.orientalis at the moment. This has a dramatic effect on ventral colouration, but in agreement with the literature, does not affect dorsal pigmentation. So, the question is, how do you make them do green?
Thats interesting, as I said my orientalis were green from the moment they absorbed their tails. As tadpoles they had a combo of a tropical aquarium flourecent tube and a ZooMed 5% tube. Then once their front legs popped through I transfered them into an aquaterrarium with just a ZooMed 5% tube but in a sunnier part of the house.
I have heard reports from people keeping B.orientalis in outdoor enclosures that the sunlight does affect the development of the dorsal coloration and that adults with a high proportion of brown if kept outdoors will turn plane green.
In general Bombina needs a lot of light to flourish and lighting definitely affects the development of the dorsal colouration of the toadlets, more specific the light-intensity: the more lumen, the better.
When raising Bombina orientalis toadlets i provide a light-intensity of at least 8.000 lumen
above their tank (tank-height only 5 inches).
Within 3 months over 80% develop a bright green dorsum. For some reason or another some toads keep a basic bronze colouration with blotches of green.
@sde, hi everybody I'm getting a tiger salamander coming from Katy Texas what are the shipping conditions that's okay to have them shipped to me in the state of Vermont it's just starting to get the temperature low above 45 but it may be too hot to ship him any thoughts or ideas on how to work this out
I currently have a 3 year old axolotl, he hasn't been eating for the past couple of weeks and has lost a lot of weight. Hedwig usually eats bloodworms and earthworms just fine but now he won't even stud it. I've done a water change to make his nitrate lower and his water is at a good temperature
Hey guys I was wondering if my axolotl looks fine to you he/she (still don’t know) I’d activate and eating as usual but I did notice veins in the tail area.. let me know what you guys think! Also if anyone could tell if it’s a boy or girl that would be great! (Zolo was eating a worm and pretty sure the worm pooped XD)
