The whole pairing process went for about an hour. The male was going around in circle, in & out of the enclosure majority of the time. The female was very calm, and patient for the whole time. Unfortunately, I accidentally pressed the button, and the recording stopped at the end. The male had three good insertions for about ten to fifteen seconds each time, and managed to exit the scene safely.
I and @CommanderBacon agreed to pair them again a couple of days later, just to be sure, then the male will be returned.
Over all, it was great success for me, to even have this opportunity to attempt pairing / breeding. It was truly amazing first pairing ever experience.
A complete breeding report will be provided once it goes either well or bad in two or three months.
It is certainly wonderful when tarantulas eat well, molt successfully, but when it comes to rehousing, it is also wonderful when tarantulas are using hides that were provided, and when making burrows out of the initial burrows that were provided.
Previously mentioned, Haploclastus devamatha was rehoused into larger enclosure with the hope that it would make a nice turret burrow out of the initial burrow I made for it. Then this happened in the morning. What a beautiful sight it is! Just as I imagined in my sweet dream. This rarely happens honestly, so I am very happy about it.
