Perhaps not the weird behaviour dept but still a bit remarkable. I have a trio of A. pertensis in a 150 litre-tank with some tetras and a couple of A. paucisquamis. My pertensis has always been monogamic even if I had more than a pair in a tank but this trio isn't, or the male isn't. He spawned both females within a week and is now helping both of them to protect their fry from the tetras. Really nice to watch and I guess he takes the chance when he can... Has anyone seen this in what is generally accepted as monogamic species? There is some confusion regarding A. pertensis and I am not sure that these are the true form even if they're very close. Does anyone (Mike?) know where/if there is a photo of the real A. pertensis in any book or online?
