Thanks guys!
The pim is about 6", I paid about 47$ (44€) for it. I wanted to get three, but they had only one left in Stock, sadly they weren't even able to order more (don't know why)
thebiggerthebetter:
you are absolutely right about the light, when I sit in front of the tank, he swims up to the front and cruises around there, but, as soon as I raise my hand to drop some food in, he darts back into his hiding place.
I mean, I don't expect him to get as tame as my Bullhead in my pond, but I hope he at least won't spook as easily, after some time, so I can "enjoy his beauty".
But well see how it goes.
I'll keep you updated on behavior changes and growth.
