I got hooked with a very small nem (black window, I believe) a few months back. My clowns immediately hosted and with regular feeding the nem doubled in size since I got it. A few days ago, I noticed I now have two! Looking online I understand this can be due to good husbandry or poor husbandry. It currently resides in a fluval 13.5 with stock lighting so perhaps I would need to upgrade eventually. Either way, I am super excited as this is my first Nem and thought I would share.
