January 2022

January 1, Gonyosoma oxycephalum:

Surely a good start of this new year! On October 19 a mating was observed and today, 73 days later the female laid 4 big eggs.

I did put the eggs in a box with moist vermiculite and they went into the incubator at 29 degrees Celsius

January 1, Corallus caninus:

My first attempt to breed C. caninus last February failed. Maybe they where too young (5 years old at that time) or maybe I introduced the male too late in the mating season?

This year I introduced the male to the biggest female in December. At the same time I dropped the night temperature during a period of three weeks and I increased the misting.

Last night there was not only fireworks outside to celebrate the new year…

January 5, Lamprophis aurora:

These L. aurora are born on July 27 2021. One of them refuses food ever since.

This picture was taken two weeks ago to show the difference in seize with one of the others from the same litter.
Much to my surprise the little one accepted food on December 31.

Today, five days later I found her dead. The prey was not digested. The remaining four  from this litter are doing very well and accept one day old mice.

December 2021

December 10, Corallus caninus:

One of my Corallus caninus females has been a poor eater over the years. Mostly she is willing to accept a prey, strangles it but then drops it after killing it. The male in the terrarium next to her is a problem-free eater.

A friend suggested that she might be distressed because the branches she rests on are on eye level. By putting the terrarium on a higher shelf my approach would always be from below and not horizontal any more. This might reduce her stress.

I followed his advice on June 17. The terrarium was put on the highest shelf so the branches came on 2,6 metres (8.6 Ft) with a remarkable result:
Look at the feeding form below to compare her eating before and after June 7!  I ow my friend a few beers..

 (BR stands for a one week old baby rat, SM = 3 week old mouse, JM = 6 week old mouse, M = adult mouse)

December 27, Corallus hortulanus:

I decided to breed with two unrelated couples of Corallus hortualus.  


Several matings from both couples observed over the last weeks

December 29, Corallus hortulanus:

On September 29 I wrote that I wasn’t sure if the second female was pregnant or not although her colour changed from red to grey. Early October she started eating again and today during shedding she produced faeces and two infertile eggs. It looks like her colour is changing again from grey to red..

The same female in September 2021..

November 2021

November 11, Zamenis Situla:
I bought two unrelated couples at the Snakeday in October.

Two accepted food several times but the other two refused the nest-mice offered time and again.

I decided to put them all in winter-rest for a couple of weeks at a temperature of 13-15 degrees Celsius.

Bogertophis subocularis:
The adult couple went into winter-rest too. Last feeding was early October, the heating went of in the beginning of November

October 2021

October 10, Snakeday:
I attended the annual Snakeday and was able to buy two unrelated, captive bred, couples of Zamenis situla.

October 14, Bogertophis subocularis:
The first three eggs hatched today after 69 days in the incubator (temperature at 29 degrees Celsius). Two juveniles are healthy, the third has congenital defect with the eye. Another four eggs are infertile. Two more to go..

October 17, Bogertophis subocularis:
I opened the last two eggs today. They both contained a dead juvenile with an eye with a congenital defect!

The final score is two healthy juvenile out of a litter of nine. That is a very poor score.

Maybe it is my own fault; I used a new box and maybe the ventilation-holes weren’t big enough. Insufficient ventilation might have caused death and the congenital defects.
The incubation conditions were the same as the recent years..

October 19, Gonyosoma oxycephalum:
Tonight I found my three year old male in mating for the first time

October 27, Corallus hortulanus:
Last night a female (check the Logbook on September 21) did give birth to a litter of 14 juveniles. They all look well and beautiful. I am used to see more colour variation within the same litter

September 2021

September 21, Corallus hortulanus:

Earlier this year I had two couples Corallus hortulanus in mating. One female is pregnant. Her skin became a darker shade of red, en her belly grew. I find her lying under the hotspot most of the time (see picture).

I’m not sure about the other one. She has difficulty shedding properly which makes it difficult to see if her skin becomes darker. She doesn’t eat and isn’t under the hotspot that often..

September 26, Corallus hortulanus:

I’m still not sure about the second female being pregnant.. She did shed perfectly today. Much to my surprise her colour changed from red to grey.. A few months ago she was just as red as the  female above…

September 28. the Snakeday is coming up..

I made up my mind about which offspring snakes to keep and which ones to sell.

The Snakeday is the only reptile-market where I have a table to sell my offspring. See the Sale page for details.

I decided to sell my Sanzinia Madagascariensis male as I don’t have breeding intentions with this specie.

July 2021

July 27, L. aurora:

Six eggs hatched over the last three days. Six eggs hatched over the last three days. From the litter of nine eggs, three turned out to be infertile. 







I kept some 2019 and 2020 offspring until this year just to see how they develop:

Just born;   length: 11 cm – weight: 4 grams

One year old;  Length: 25 cm – Weight: 11 grams

Two years old;  Length: 45cm – Weight: 29 grams

June 2021

June 5, Lamprophis aurora:

L. aurora laid her eggs today in a box with moist moss (spagnum). Nine eggs in total, all but two look good. The eggs are in the incubator at 29 degrees Celsius and I expect them to hatch at the end of July.

June 16, Bogertophis Subocularis:

Several matings observed over the last couple of days…

March 2021

March 15, Corallus hortulanus:

I want to breed with two couples this year. Early March I introduced them to each other and several matings observed until now. The female on the left thought mating was more important than finishing her shedding first..

This morning I found both couples in mating.
What a nice view to start the day with!

February 2021

February 28, Corallus caninus

My 1.2 Corallus are over five years old now. For the first breeding attempt I introduced one of the females tot the male. Within minutes the male was interested in her but she was not amused, tried to escape from the terrarium and went eventually down to the floor and stayed there. She even tried to dig herself in. I separated the two the next morning.

After a few days I introduced the other female to the male. This female showed exactly the same behaviour. I separated them too and will wait a while with the next attempt

February 18, Corallus hortulanus

All but one of the September 2020 Corallus hortulanus offspring are eating. I am not worried about the last one. He comes out of his shelter and is interested in what’s going on.

I expected it to be a matter of time before this one will accept food as well

(Two days later the first prey was accepted..).


February 12, Bogertophis subocularis

Bogertophis subocularis is out of their winter rest. After two months they are back at room temperature.

I’ll put the heating on in a two weeks time and start feeding them again in the month of March.
