NICE!! Yup, thats what i thought they looked like! Those are the best color strain of marms out there in my opinion. LOVE the Rio Tapajos marms. WOW! I'm gettin at least three of them!!
I have to agree though, i am starting to like lents. more now that I have seen more pictures of them...lol....they have a lot more red and kewl stuff than marms. But marms definately hold their own. My water parameters when i got my xingu III to breed was about 6.8 pH...moderately soft, i had been feedin them live earthworms and live prawns....pinchers removed. This really beefed up the female. You could easily tell she was gravid cuz she was PLUMP. They did get aggressive as hell though when they laid eggs. It was in my 125. And yes, the male almost killed my female two or three times....luckily i had a few hidin spots small enough for her. I used this HUGE clay pot thingy inverted. It already had holes in it big enough for them to fit through. Definately try the light thing. Before you do it though do a water change, drop the temp about 4 degrees at least. Then do the lights. That should get a reaction...
