I just got my new Black Ghost Knife in the tank - took an hour to aclimate him . He is about 4-5 inches long and found a nice little spot in the center of the tank to hide (between two rocks) all I can see is his tail wiggling ,I'll have to wait a couple of days to get him out enough to get a picture . The
LFS had two of them there -can you put two in the same tank?
