Hi,
o.k., I'll tell a bit more about my pets......
My actual stock concerning rays ist:
1.2 Pot. leopoldi
1.3 Pot. henlei
6.3 Pot. henlei x leopoldi
1.2 Pot. spec. 'Pearl'
4.5.8 Pot. scobina
0.1 Pot. spec. 'Itaituba' (P14 or R150) soon 1.2 again! I've been so silly to sell my breeding Pair because of my wife

and because of a lack of space in my former tanks

Now, because of the still rising prices for rays, I've been able to convince my wife of the need for more tank volume

not to earn lots of money, but to pay most of my hughe and also still rising costs with some of the pups......
0.1 Pot. motoro 'Marbled'
0.1 Pot. motoro 'Orange spot Peru'
Until now I had breeding success in Pot. motoro (about 10 litters), Pot. spec. 'Itaituba' (only one time, bevore I've sold them

), Pot. scobina (about 15 times), Pot. henlei x leopoldi (4x), Pot. henlei x motoro (6x) and now, finally also one of my Pot. henlei seems to be pregnant from a male of her own species. And my male leopoldi from Sao Felix do Rio Xingu is also getting adult at the moment......
My rays are placed in 8 tanks with a total volume of nearly 20.000 Liters but at least two more tank à about 2500 Liters are following soon.
I never had problems with any of my Loricaridaes as L007, L14 or L27 (do you also use L-Numbers here

or are they only common in germany?)
After I've read most articels in the stingray part of this forum, I hope I'll be able to write more understandable, sorry till then
Regards
Stefan
