Hello, I'm a bit confused about my severuma.. One I'm sure is rotkei, another 2 I have bought as a rotkeil long ago as a tiny creatures, they grow very slow and they never got any red colour, they look yellow blue. On the picture 2 are strange growing slow and a rotkei as you can see also young but having red colour. I guess rotkeil will be a female ? Could you please identify what is another 2 and sex of them 3. Thank you in advance.
