New addition to my 10gal

the cherries are neocaridina and I'm pretty sure these guys are caridina (Crystal Blacks or Bee shrimp? both caridina anyway). They won't interbreed. Dunno how to sex them if you can't see saddles, though. I know males are generally smaller than females and less colorful but I've never liked trying to differentiate sex by looking at size. How can one know if it's a small female, or a juvenile or something, you know?

i agree with you, sometimes its really a guess, but then again, i have no idea, i hope some of the pro can come in and tell us how to sex them...
