I don't know a lot about the species, getting into them a lot lately. I was wondering how many out there have bred any of these guys. Have any tips or examples to give? Good or bad! I need any advice I can get but of course I am continually doing my own research everyday. A big question I had in particular is can any of the mastacembelus variations interbreed with each other? I probably will be back later to post pictures of the ones I currently own to try to better identify them, but I know they aren't the exact same subspecies. Really would love to give breeding these a shot, they are such a cool fish! Thanks in advance!
