okay last night i went to my lfs to just look around and they had kribs in. so i had gottin 2 of them (male and female). i have been waiting for my lfs in get them in again. anyway by the time i added them to my tank it was time to turn the lights off, so i didn't really get a good look at them in my tank. so this morning when i got up they where swimming around the tank together (side by side). and i think they are my new favorite. they are so much more beautiful once they get home from the lfs. anyway to get to my point is there a chance i can get more of them or are you only suppose to have 2 to a tank.
