Hi guys and gals! I have been reading and really enjoying all your information and humor on this site for a while and you all inspired me to start keeping aquariums again! Thanks everyone for a great, friendly and extremely informative site... Can anyone help id this little bugger, and let me know if this wee thing is harmful? This little one is about the size of a sunflower seed. I have also found an even smaller baby version just today. This is in my 1.5 gal nano freshwater tank housing 8 shrimp + 2 baby snails. Thanks!
