Tonight I acquired two fish and I have NO CLUE what they are. Normally, I'd be super careful about what goes into my tank, but I was in a market (I'm an American expatriate who lives in China) and someone was selling tiny, sealed bottles with fish trapped inside! ACK! All but two of the fish in the bottles had died and the two who hadn't looked like they would not see tomorrow so I bought them and brought them home. Since I wasn't expecting company, I didn't have anywhere to put them but in my 15-gallon tank (not sure on the size, it's plenty big for what lives there) already inhabited by Stanford, a 4-year-old Chinese algae eater, and Renoir, a 1-year-old male Betta (they get along surprisingly well all things considered).
Anyway, my major problem is I have no clue what these two fish are and if they need any special care. I'd have gotten a pic, but at the moment, they're both joyfully darting back and forth and playing in the flow from the filter outlet, fleeing from Renoir who's trying to check them out to see if he needs to attack, and basically moving way too fast to catch on camera. I'll put up a pic as soon as they calm down, mostly because they're absolutely stunning.
My first impression was they some kind of danio. They're tiny, less than an inch long, with sleek, dart-like bodies and nearly clear, non-descript fins much like a neon tetra or zebra danio. But what really throws me is their color; their bodies are a dramatic, eye-popping hot pink! Their undersides are a lighter shade of pink and they both have nearly invisible, shiny pin-stripes from gills to tail also in a lighter shade of pink. and their fins are also shot trough with the same iridescent pink which is only visible when they are in full light. So they have zebra danio markings in a color I've never seen before. It's obvious that, considering the inhumane circumstances they've been living in, they're probably thin from malnutrition and they're probably not fully-grown (at least I hope not, getting bigger will certainly make them more beautiful). Ideas? And if you know what they are, what can I do to take care of them?
