Thank you, Helene – I think I feel the same about this possible male, I am still not totally convinced that it’s a female. But still it’s Martin Hallmann who says so ……
I can not really contradict Martin at this time ……… the fish are still vey pale in the new tank, but this may still be due to the new surroundings and the leaves on the ground, which are a light golden brown and not as dark and reddish as in the other tank.
I can only say that it’s total harmony between these two – although it’s the “wrong” small one I caught, not the one that possibly showed courtship colouration.
There’s no chasing at all, they swim almost always together, explore the smallest space beneath leaves together and seem to be “delighted” when they meet each other. And the big one is visiting the caves and always staying in there for a while.
The two other ones left in the old tank which rather surely are females, are as bitchy as before, prodding each other in the sides and chasing one another over short distances. Most of the time they stay separated from each other.
