Do you feed your fish, thawed frozen foods?
Loss of vitamins and minerals due to food transport, storage, and preparation may make vitamin and mineral supplementation necessary.
Studies on oyster meat that had been frozen for 6 months showed losses of 22% of vitamin B1, 35% niacin, and 46% pyridoxine.
Another researcher found 45-98% loss of water-soluble vitamins from pelleted shrimp food after one hour immersion in seawater.
In general, the smaller the food particle, and the longer the food remains uneaten in the water, the greater the loss of water-soluble vitamins.
This is why, at all public aquariums, the sharks and rays (and many of the other megafauna) routinely receive nutritional supplements.
Your fishes at home might also benefit from such nutritional supplements. But the problem with many of these nutritional supplements is that they come as large tablets that’s impossible to feed to smaller aquarium fish.
Thankfully, nowadays there are several manufacturers who make multivitamins for fish.
