I did it!
I did it like before with other fish ……….. first of all patience, second a net deposited quietly in a free space of the tank, wide open and easy to lift.
The first small one I caught by putting some blood worms into a medium net. It was very easy……
The bigger one was not so easy, but that was my own fault. I let im visit the net to get him acquainted to it – but obviously once to often. He lost interest and didn’t visit it again …….. for hours.
So I took the net out, put a real big and wide one in, with the opening facing upward. I had to wait three minutes, than the big one and the other small one swam over the gap and into it ……. I only had to lift the net and put the small one back into the tank.
I do not know which of the small ones is with the bigger (male?) one now – is it the one which already showed kind of courtship colouration? I am able to distinguish them by the form of their pelvic filaments, but not in a small vessel, looking from above……. The other small one I put back into it’s original tank is hiding at the moment …. :blush:
But I think it is a trial, anyway …….. I only presume that all other three are females ……… I am still not sure with the second largest. But now I hope we will see ……….
