So i bought a pistol shrimp and a goby the other day from a LFS, they were living together in the same hole at the store so i got all excited and bought them. The problem is not they are not living together now in my tank. I can see the hole in which the pistol dug, but the goby cant seem to find it. Now i understand that this is me being a brat, but i want them to co-exisit darn it! Is there anyway that people know to help them find each other? Its only been a week and i know thats really not that long, but again im being a brat right now
