All Bettas love live food. However, feeding your fish freeze dried food is much more convenient and cost-effective. Pet stores sell specialty foods and Food for fish. Try mixing your pet fish foods and supplement them with alternatives. Don’t just feed them the same food over and over again. They will require alternatives to supplement and make-up their daily staple food. You should always try and supplement their meal time with freeze-dried mosquito larvae (e.g. known as "bloodworms") or natural brine shrimp.
Betta Fish Live Food
"Mosquito larvae" is considered the fish’s natural and very digestible food. Also, "red mosquito larvae" known as "bloodworms." Fish just love to feed on live "brown worms" and many fish go wild on blood worms.
However, these live foods are really notorious for carrying disease and bacteria. This also applies to many other types of live foods. If you wish to feed your pet live worms, be certain to wash the worms in clean water and thoroughly. You should never give your pet worms taken from your garden or worms you have caught in the wild because you are taking a big risk as these worms almost always carry harmful pesticides.
Side point: Inexpensive Brine shrimp is also a favorite food of Bettas. You can feed Brine shrimp to your fish as an occasional treat but keep in mind **ONLY** feed it in moderation. You can feed your pet freeze dried brine shrimp or you you so desire you can hatch them yourself from accumulated eggs.
Frozen Fish Food
Frozen food is a safer bet than say live food, as there’s less likelihood of catching disease and even fin rot. But its still not as easy and friendly to use as freeze-dried. Most fish can go a day or two without eating anything at all. So, you shouldn’t worry about leaving your pet for the weekend. But if you intend to be away for a much longer period, then be sure to have a friend or relative stop by and feed your pet. A good alternative is to purchase a time-release fish food block (and/or an automatic fish feeder) from your local pet store. If you decide to go this route then make sure that the fish’s water is clean and okay. If you are intending to be away for several days and wish to use a slow release food block it’s probably a good idea to replace all of the water with fresh water.
Fish Digestive Tract
If your tank is much smaller than say 5 gallons you should consider cleaning it before you plan your weekend away. As we’ve mentioned before it’s also a good idea to clean your tank or bowl at least once every week. Side point: It’s good practice to allow your pet to fast by skipping a day of feeding say once every week. Why? Because it will allow your fish’s digestive tract sufficient time to recover and clean itself out on the inside.
Note: Some fish tend to stop feeding on dried or frozen food once their satisfied and full. However, they’ll continue to gorge themselves as long as there’s live food in their aquarium. So, *DON’T* overfeed your fish with live food or they will quite literally eat themselves until they actually die. If you notice that your fish has developed a paunchy look and/or a swollen belly, this is an indicator that you’re overfeeding your pet. But if your pet appears somewhat gaunt or thin in appearance it may have a serious infection or even require more wholesome food. Helpful information about fish for sale.
