Feed Tropical Fish FAQs
1. How much food to feed tropical fish?
The best way to think about feeding tropical fish is to consider how they would naturally feed. Think about it.
If you are used to eating 3 small meals a day and someone offers you a whole pizza for dinner but nothing for breakfast or lunch, your body wouldn’t adjust well. You’d probably eat way too much pizza for dinner then feel a bit ill.
Then, by the time breakfast and lunch came around, you’d be starving again. It’s the same with fish. You should feed them similarly to how they would naturally feed so they’re comfortable and getting the right kind of nutrition.
A good general guideline to follow is 3 flakes per fish with every feed. Believe it or not, you’re more likely to overfeed than underfeed so, as long as your fish seem healthy, they’re probably getting enough food.
Keep in mind that this is just an estimate and it depends on the size and age of your fish, the size of the pellets, and how often you’re feeding them.
A good rule of thumb to figure out how much food you should give your fish is to let them have whatever they will eat in a 2 minute period. If they scarf everything down in 30 seconds, they’re probably still hungry.
On the other hand, if there’s a lot of food left after 2 minutes have passed, it’s safe to say that you’re overfeeding your fish.
2. How often to feed tropical fish?
As we mentioned, about 3 flakes per fish per feed is a good amount to give your fish. But how many feeds should you do?
Again, try to stick to their natural routine. In their natural environment, tropical fish aren’t going to eat on a set schedule. They eat when they find food. Sometimes, that might be a few times a day or they may go a day or two between feedings. This makes it a little difficult to keep tropical fish and is one reason that it’s important to pay close attention to how much and how often they’re eating.
The best way to replicate natural feeding is to feed them small amounts about 3 times a day. And remember that every fish is different so do some research on the fish in your aquarium and try to match their natural patterns.
As we mentioned, you’re more likely to overfeed your fish than underfeed them. That’s because it’s kind of hard to understand that they don’t need to eat that much. But, if you think about how they live in the wild, it starts to come together. In the ocean, tropical fish only eat when they come across food. That could be a few times a day or a few times a week. Whatever the case, their bodies know what they need.
In a way, that’s why it’s so much easier to overfeed them. The fish are eating so much because it’s there. They don’t know that it’s going to be there again later on or tomorrow. Believe it or not, some people actually skip days during the week by only feeding their fish every other day or only 4 or 5 days a week. Fish can thrive like this because there’s less chance of overfeeding.
3. How to feed tropical fish when on holiday?
That depends on how long you’re going to be gone.
Remember, fish don’t eat every day in the wild so if you’re going to be gone for a long weekend, they’re just fine if you don’t feed them. This might seem mean or cruel but it’s what the species is used to.
Plus, some people actually incorporate a fasting day or two for their fish throughout the week so letting them go hungry for a few days isn’t typically a problem. The one exception to this is if you have young fish. The younger the fish are, the less fat they have stored which means they won’t have the reserves to last quite as long as older fish if they’re not fed.
If you’re going to be gone for a week or two, it’s probably best to make some feeding arrangements. There are a few options.
First, you can find a pet sitter to come to your home and feed your fish. You can work out a schedule that works best for them and your fish and, since they don’t need to eat every day, a friend or family member that you trust would probably be willing to help you out.
Another option is you can get an automatic feeder. These are machines that you can set to release food into the water at a set time. Some of them you can program for up to two weeks at a time!
A third option is to get a vacation feeding block. These are basically large blocks of fish food that have been designed to slowly disintegrate to release a few flakes at a time. There isn’t an exact science to how fast and how often the block will release food, but it’s a good option if you can’t find anyone to feed your fish.
There is something to consider this option, though. Not every kind of fish food is available in block form so you’ll have to decide if it’s worth the risk of introducing new food to your fish while you’re gone.
4. What to feed tropical fish when out of food?
If you run out of food, there’s really no need to panic. Most tropical fish can go a week or two without eating anything so you don’t have to try to come up with alternative food options. Just wait until you can get to the store and they will be fine.
Tropical fish can eat a few things from your kitchen, depending on the type of fish. You should research the specific kind of fish you have to figure out what’s safe and what isn’t. That said, most tropical fish can tolerate peeled peas, spinach, or lettuce cut up in small pieces, and even cucumber and zucchini diced into tiny pieces.
While these foods are a nice treat for your fish, they shouldn’t be included as part of their daily diet. Once or twice a week is fine but tropical fish foods are formulated to give your fish exactly what they need nutritionally and don’t require any other supplements.
Conclusion
The best quality tropical fish food will keep your fish happy, healthy, and beautiful. Any of the foods we reviewed would be great for your tank but our top pick is Tetramin Tropical Flake Food. It’s formulated with the vitamins, minerals, and proteins your fish need to thrive.
Another problem with over feeding your fish are the chemicals released from uneaten rotting food. Ammonia is probably the worst. You water may become cloudy as well. You will have to do water changes more often should either of these occur.
