Yes, I am a new member and this is the first post. 
I have two tanks, one 600l and the other 180l (150g & 45g, I think)
The bigger is a mixed African setup with Asian influence and the smaller is a mixed South American.
Species: Synodontis decorus, S. schoutedeni, Ctenopoma acutirostre, Black ghost knife (not African I know), Congo tetras, Mastacembelus circumcinctus, Anaspidoglanis macrostoma, Crossocheilus siamensis, Hoplosternum sp. Panda Apistos, zebra pleco, l-200 pleco, small tetras and some corys.
Looking to get next: Polypterus senegalus or P. palmas for the bigger tank.
Question: which one of these is the more peaceful species?
Had an P. senegalus before but lost him for unknown reason (maybe he over-ate). He was the best fish ever and after months of mourning I now thinking of getting a new one.
Anyway, here´s the introductions, nice site and nice fish u people have!
