This is great since Malabo has wildborn arents with no or only 1 other offspring, so he is genetically very important.
As far as I can see, Malobo(Bioko x Nadia) has only one half-sibling- female Banga(same father Bioko, different mother) 'Banga' was to be moved from Madrid, probably to Givskud, Denmark though at one time she was going to London... (she is very bald, as she has Alopecia...
I also heard that Awali(formerly in Paignton) at Barcelona has so far proved 'no good'- he was handreared and relates to the keepers.
