Most tropical fish species can go several days without food without experiencing adverse health consequences, but they still must be fed regularly to remain healthy and vibrant.
One solution may be to enlist the aid of a friend or neighbour to feed your fish at specific intervals throughout the day, provided they know and understand your species well enough to provide timely feedings at regular times.

Feeding
One of the main concerns for fish owners when leaving on holiday is how to feed their aquatic friends. If this is an option for you, having someone come and feed them would be ideal; alternatively a battery powered automatic feeder can also work very effectively by dispensing food on an automated timer for up to 2 weeks at once – be sure to fill this dispenser before departing so it has enough food for its intended duration – otherwise an untrained sitter could overfeed your fish, potentially leading to bloat or water quality problems!
Fish food designed to last up to two weeks should also be placed in your aquarium; however, as fish tend to devour it quickly and starve themselves before returning home.
Water conditions
There are various strategies you can employ when traveling with fish on holiday. Your best choice will depend on both its length and species.
Some fish, particularly sedentary carnivorous ones, may survive up to three days without food, drawing upon energy stores in their muscles and fat stores to access energy reserves when necessary. If your fish become especially desperate for sustenance, however, they may start devouring other substrates or fish as food sources.
Aquarium shops commonly sell holiday feed blocks designed to store enough food for several days at once. These ‘holiday feed blocks’ typically consist of plaster-of-Paris that slowly dissolves in water, dispensing small morsels of food over time. Unfortunately, their use can raise hardness levels in tank water, leading to ammonia spikes and algae blooms.
An effective solution would be a small automatic feeder which can be filled with pellets, flakes or sticks and will gradually disperse them over a number of days. They tend to be economical and straightforward in their operation – just ensure it works before embarking on your holiday trip!
Lighting
Some tropical fish species, like mouth brooding cichlids which carry fry, can survive without food for extended periods if provided sufficient light and energy stored within muscle or fat tissue.
If your aquarium or pond is small enough, and you have a friend or neighbor with experience in fish keeping, asking them to feed the fish once or twice every day could be beneficial. But it should only be done if they can be trusted to understand your water conditions; otherwise it could become easy for them to interpret frantic swimming as hunger signals and overfeed them, posing health risks.
One option is a battery operated automatic feeder with a hopper for filling with food of any kind, with dispensing schedules from once daily up to two weeks or beyond.
Water temperature
Knowing your fish well and providing it with appropriate food can be key in their wellbeing. Any misfeeding could result in health issues for the aquatic life in your tank; to be safe it’s best to ask your local Petbarn team what their preferred types are as preferences vary between species.
Water temperature plays an integral role in maintaining your fish’s wellbeing, impacting on its metabolism and digestion as well as many other processes. Therefore, it’s essential that you conduct thorough research in order to ascertain which range is ideal and whether any deviation can cause issues for them.
Some fish, particularly cold water varieties like goldfish and carnivores, can survive up to several days without food. If you want to give your fish a break from feedings for holiday breaks, special holiday feeding blocks may help as they gradually release food over time – however be wary as many contain chalk which could leave your tank filled with dead fish when you return home!
