I just bought some amano shrimp to put in the tank that will eventually hold my fancy goldfish and two mystery snails. However, I'm worried about my goldfish possibly trying to eat the shrimp. I got the biggest ones they had (about an inch), but my goldfish is obviously still much bigger (maybe a little more than two inches, not including the tail). How do I best protect my shrimp and keep them from getting eaten? Here's a picture of my tank now. Do I need more places for them to hide?
