thanks for reply... i will get them later. :lol:Raul-7 said:The male has a yellow border that extends along the edge of the male's anal and caudal fins. You shouldn't house them in nano-tank, way too small..and unstable conditions. The minimum you should use is a 15g. It's probably best to house them in a species tank, although you will encounter male causaulties, so get between 5-8 in a 15g.
can you tell sex? i have 6 species of Nannostomus sp. only one species i can 100% sure that i have two pairs, others i couldnt tell their sexes! i like the way how N. eques and N. unifasciatus swim.tsunami said:I have a trio of Nannobrycon eques (tube mouthed pencilfish) and four Beckford's Pencilfish (Nannostomus beckfordi). Nothing too special.
So does the female. IMO, sexing is nearly impossible with osphro's until you can get them to spawn, which is quite difficult (I nearly killed myself and quit the entire hobby trying to do so). However, over in Europe they seem to just wave a magic wand over the tank and the fish are holding the next morning. Speaking of...The male has a yellow border that extends along the edge of the male's anal and caudal fins.
