The reason I used this title was because a friend of mine that regularly contributes to this forum thought they were hybrids, It did actually say on my email to him that they were Hystrix, he obviously never saw it. This got me thinking, I wonder if anyone else would think they are hybrids, this thread confirms that many of you did. I have to confess I too think the intricate pattern on these is very different to the norm, in particular with one of them. The mother is only a small girl of approx 10" and the male is tiny, 7" disc, he might be small but he is a real randy little devil. There are 3 females in the tank and 2 males, no other species are present so there is no doubt to the fact they are pure.
Thanks to all that contributed, I wasn't trying catch anyone out...well not much..LOL! I was more curious as to what you guys thought, a few of you lads have Hystrix yourself as I know, I'm sure the title had something to do with making your minds go into overdrive, so many hybrids about these days.
