I know that maintaining your fish’s health is a higher priority for you right now since you are taking a vacation. The following is vital information on the ability of your fish to survive without feeding.
How To Feed Fish While on Vacation?
Before departing on a trip, you must prepare for several essential aspects of your fish’s survival arrangements. When planning a vacation that involves being away from home for an extended period, fish keepers have a few alternatives available if a question like “How long can fish last without food?” crosses their minds.
Below, you can get to know about both feeders for your fish:
Both battery and electrically operated versions of automatic feeders are available in the market nowadays. Throughout the day, at specific intervals, these feeders are equipped with timers that are automatically programmed.

The food holding dispenser allows an adjustable-sized aperture for predetermined food quantity. Scheduling the specific diet amount and adjusting the timer before going for a vacation is now possible with these fish feeders. If you are leaving for longer, you need a big-sized feeder with more food storage ability.
Vacation feeders come in two types. The first one stores gel, and the other store’s calcium for fish. It depends upon how much food you need according to different fish types. Three specific sizes allow you to go for a 2, 7, or 14-day vacation. However, I have discussed below how much each fish type can survive without food using its fat reserves.

Betta fish can live without food for up to 7 days if the circumstances are right. But you should never do this for longer than that. They may survive for a few more days; however, this is only applicable to keeping them alive, and you are genuinely starving the betta fish, which might lead to their passing.
How Long Can Guppies Go Without Food?
Guppies can go up to 2 weeks without feeding before dying. Isn’t it just incredible? Adult guppies survive for a more prolonged period than adult betta fish do.

We cannot endorse the practice of denying food to your guppies, so please do not make this a part of your routine.
On the other hand, if your guppies are still relatively young, it is not in their best interest to go without food for such a lengthy period. Guppies in their early stages of development must consume their food consistently to reach their full potential. They are more sensitive to being neglected when it comes to food.
They do not have the same capacity to store food and can only do it for a shorter period than adult guppies, who can do so for up to two weeks. Guppies that are older, larger, and healthier have a better chance of surviving than guppies who are younger, smaller, and less healthy.
How Long Can Tetras Go Without Food?
If you plan to deprive your tetras of food for more than a week, it is unlikely that you will find them still alive when you return to get them. Tetras do not have the capacity to live for more than a week or a day above. Tetras are endemic to the Amazon, a region known for its fast-paced culture and flowing rivers.
Because of this, fishes are always on the move, and it takes a lot of energy to maintain this activity level throughout the day. When there is a higher need for power, there is a corresponding rise in the amount of food that must be consumed to meet that demand. Since they cannot retain fat for about a week at a time, you can’t ensure their survival. That also explains how long fish go without food on amazon.
On the other hand, most keepers are under the impression that due to their small size, they only need a moderate quantity of food, which is partially accurate. Tetras are notorious for their ravenous appetites and will eat whenever they have the chance, regardless of whether or not they are complete.
How Long Can Glofish Go Without Food?
Glofish survival without food varies with the types that scientists have identified till now. Here are the types of glofish and their capacity to survive without eating:
- Glofish Tetras
In a tank that has been appropriately set up, glofish tetras may live for up to 3 weeks. If the fish tank you keep your glofish tetras in does not have any plants, then they will only be able to last 7 days without consuming any food.
- Glofish Danios
Glofish danios have a significantly increased ability to endure without food for several days. A glofish danio can go up to 2 weeks without eating. Compared to other fish found in a water tank or pond, they have a better capacity for storing fat. However, this does not imply that you should do this to your danios daily since doing so might lead to severe diseases or even death in some instances.
- Glofish Bettas
Fish keepers are particularly fond of glofish bettas because, compared to other fish, they are more resilient. Glofish and Betta fish may go up to 14 days without eating anything if they are kept in an environment that is well-maintained and contains natural elements.
Because of their enormous fat stores, they can live for longer, and their generally healthy character also contributed to this. However, using lipids that have been stored will ultimately lead to any ailment that affects glofish betta.

However, this number is highly dependent on their age. Because they are descended from rainbow sharks, glofish sharks usually seem to be in excellent physical condition. However, the health and survival of glofish are also affected by many other factors, including the pattern of their feed, digestion, and water temperature.

If a small number of fish contains smaller specimens in an outside pond, you can leave them while going on a vacation. The smaller number of fish with small size urge to find their food by themselves. They feed on small specimens like larvae or insects. However, if you have a large number of fish, especially which are significant, then you have to provide them with a bulk of the food.
A healthy fish can survive from 3 days to a week in a healthy aquarium set up with all the necessary factors like water temperature, planted tank with perfect pH of water, etc.
If we mention a healthy tropical fish in an aquarium, you cannot leave a fish without feeding it for more than 1 day up to a week. However, this is entirely dependent upon the surviving ability of fish with its fat reserves.
Each type of fish in your aquarium has a different level of fat reserves. Leaving your fish tank without food for more than 1 or 2 days will cause your fish to starve and catch any disease. Your fish can also perish if you keep up this activity regularly.
