thanks for the kind words, i did infact pair them at the LFS before i bought them. They have yet to mate and i hope i can induce mating<crosses fingers> by having the nem.

it depends on your lighting and flow. If you have MH and high tank turnover you should place the nem in a crevice, as i have in the pic above, with a small overhang to help with the light acclimation to MH. If the nem doesn't like the spot he will move on his own
