Hi,

Finally my oldest histrix is pregnant! The male is the one close to her on the picture.
I can see a lot of movement in periods during the day (specially in the evening and night, for some reason). I just tried to make a clip to add in this post, but at the time i was filming the babies barely moved at all. Ill post a clip as soon as i am able to capture the movement from the pups.

Im planning on removing the pups when they are born, putting them in a 115 liter / 30 gallon aquarium with no lighs. And set the temperature to about 28 celsius / 82,4 fahrenheit. Feed them with frozen bloodworms, mysis, artemia, and maby some big daphnia. Water parameters will be as they are in the parents tank; pH 7, GH 1.
Sounds good?

To see this stingray pregnant is the biggest thing i have experienced in the aquarium hobby, since the day i bought her 6 years ago :) Im thrilled, and hope everything works out well.

Congrats man!
 
Congrats! Yes, that is the best hystrix. Any idea how long she has been pregnant?
I was wondering not too long ago if this ray was still around. Glad she is!
 
Hi, thank you.

I am not sure exactly. I had the tanks running on low gear during the summer months, meaning i fed less than usual, with food that have less fat/protein. Started feeding them on heavy loads of freshwater herring (Coregonus albula) again somewhere within the month of august.

So if i assume that this was the factor that did the trick, i can assume that she is around 45 days in her pregnancy, at best. But it could be that the male nailed her earlier of course.
