Its 50-55mm without its tail. Female is about 10mm larger. I used to have a species tank of limia perugiae but decided to clear them out and replace them with these instead.
Here is a pic of one of the male perugiae before I moved em on.
I never bother correcting spelling usually, but it is really important to spell the names right otherwise google will never show up any information on them, as I found out when I spent 6 months spelling Limia melanonotata, melanotata
I had these for a while. They are a nice peaceful fish. There is an article coming up in the BLA Magazine soon on them.
