ok well as for the tails flowers are born with roughly 5 black and 5 white bands after the stinger.. As they age predators and/or mishaps can cause the tail to break and it doesn't grow back. All 3 of my flowers have different tail lengths. When I got my big girl she had 3 black and 3 white bands. She only has 2 of each left after my endlies got to her, GRRRR.. Color is a huge thing with flowers and it tends to vary greatly.. i have 2 that look similar and one that looks completely different. i started a thread requarding color and no definitive answer was established. I tried from barebottom to a black sand and not much happened so... And as for the little black dots I think I know what you mean cause as my big girl aged she got random solid little black dots that popped up in weird places and stay there. Had one at first and now she has probably 5 or so.. very weird and I have concluding its not harming her but no idea honestly. Hope someone can answer this. Hope some of this helps
