I have 3 guppies and 3 amano shrimp in a 10-gallon. The shrimp were added several days ago. I bought shrimp granules for food rather than the wafers (not sure if that's what they're called). My problem is that the guppies eat the food before the shrimp can even get to it. Some of it doesn't even make it all the way to the bottom of the tank before piggy guppy swallows it whole! I'm worried it will constipate the guppies, overfeed them, and the shrimp will have a poor diet. How should I be feeding them? Do I have the wrong type of food? Am I using the wrong method? Any advice would be greatly appreciated.
