Thomes........A. gibbiceps have diagonal stripes on the belly. I know that sound kinda goofy but once you've seen them and know what you are looking for you'll never forget them. If the male already has the lyra tail the stripes should be there!! Theyu would go from about the gill to the anal fin....that direction and there should be 5-6-7 of them.....otherwise it may be a A. bitaneia (my spelling???)! If it is A. gibbiceps yes LOW pH and very soft. Good luck Mike - -- .....................................................................................................................................................
