What species is it???We all enjoy a good leech, although that one will eat inverts it can fit in its mouth....
Speciating from a picture is a bit much for me ?, but most of the fresh water leeches are predators and fish leeches are really distinctive. Pretty easy to keep though, I had a couple come back alive after being in ethanol when I put them under the light scope ?.What species is it???
I know people commonly keep hirudo species as pets but this doesn't look green enough....I don't know though. It's sort of olive green/brownish. But maybe too green for an erpobdella species - and thats as far as my leech knowledge goes so I have no idea lol
