So I'm probably going to change my gravel today and yesterday my mother went out and bought a load of tiny cherry shrimp. She thinks there must have been almost 20. In my tank I have a piece of driftwood. Obviously I will be removing this to change the substrate but I think all the shrimp are hiding in it. How am I going to do this? Do I just take it out and put it in a bucket? I don't want to lose or accidently throw away any shrimp! Some are really tiny too.
