Have you ever gone to a fish store and looked into the fish tanks only to see listless and lethargic fish with drab colors.
A lot of time this is from the fish not receiving a high protein diet. Most fish food is full of dried foliage flakes of little to no nutritional value. I have found if you want your fish to really come alive, give them brine shrimp. It is very high in protein and the fish absolutely love it! Another great nutritional alternative is blood worms. It’s a bit messy because a lot falls to the bottom before fish can eat them.
