Week 41: Feeding fish - Selecting food for maximum health & longevity | 52 Weeks of Reefing #BRS160
While fish can survive in a lot of different types of foods their biologic functions have evolved around utilizing a certain mix of proteins, carbohydrates, minerals and vitamins. This is pretty similar to other pet foods. For instance many pet owners acknowledge their dogs and cats are carnivores and make an attempt to feed them protein rich foods which have minimal to no grain diets, many take it a step further and feed low carbohydrate or even raw foods almost completely comprised of the entire animal bones organs and all ground up to supply a very natural source of protein, minerals and vitamins.
At the highest level you have you basic categories of fish. Your carnivores and your herbivores Carnivores primarily diet being flesh which is very protein rich, and herbivores diet being primarily algae or plant material. In reality a good portion of fish in the reef aquarium are omnivores which mean they consume both algae and flesh.
So the first step in all this is recognizing the natural diets of the fish you selected for the tank. For the most part it is somewhat easy to recognize just from their behavior in the tank. Most of the herbivores or omnivores like tangs, some blennies and rabbit fish spend a majority of the day obviously looking for algae to peck off the surface of the rocks.
Carnivorous fish primarily eat flesh and this is pretty obvious with frozen foods clams, shrimp, squid and similar items which are all obviously meaty flesh of some type. While most fish will do best with a varied diet if you are going to select one you should do so my nutritional content. The food blends like the mega marines which have been fortified with nutrients do a great job of including a varied diet with a high protein and essential fat content but I think the most popular with seasoned reefers is the Canadian Mysis shrimp because it has a naturally high protein and fat content and doesn't need to be fortified.
So which foods do you prefer to feed your fish? Let us know in the comments area below, and be sure to vote in our latest poll by clicking the "i" in the upper right corner of the page.
