it's a long time i'd written and posted anything here and anywhere else in the forum ... the job kills time!
I've searched for some older pics and found some.
Here are some - they are showing a very strange community: Polypterus teugelsi and Channa gachua! It seems a bit anthropocentric but they seem to be good friends, they are together most of the time and the Channa is the one and only fish in the tank who isn't bitten by the Teugelsi (these bites aren't harmful, i think it's a territorial behaviour).
