Supa Holiday Fish Feeder

Supa Aquarium Holiday Fish Food: Best temporary fish feeder

Have peace of mind that your fish don’t go hungry while you’re on holiday

Power supply: N/A | Maximum food supply: up to 2 weeks | Feeds per day: Miscellaneous | Food type: Dissolvable

Packs of six
Feeds 10-15 fish
Suitable for tropical and cold-water fish
A bit chalky
Can't control feeds

If you need a quick fix while you’re away then this Supa Aquarium Holiday Fish Food is a good option. The block will slowly dissolve in the tank to release food throughout the day, and provides enough food to feed 10-15 fish for up to 14 days. 

However, this really does depend on the appetite of your fish and the conditions of the tank. Ideally, this fish feeder works as it says it does in a tank no bigger than 45 litres, with an average temperature of 20-25 degrees Celsius. If the tank is any hotter then this can accelerate the dispensing of food as it dissolves quicker. 

While the downside is you cannot control how often it dispenses the food, if you have a few fish that are quite independent and not that fussy about their food then this would work well for them. 

The chalky texture means the tank will need cleaning, but with six of these fish feeders for under £10, it’s the perfect quick fix to keep your fish well fed while you’re away. 

The food particles are nutritious and safe for both tropical and cold-water fish, but do not use in marine tanks. 

How to choose the best fish feeder

When choosing the best fish feeder, it’s important to consider the nutritional needs of your fish. If you have lots of fish then you will need to opt for a feeder that dispenses multiple times a day, in which case a battery powered or rechargeable feeder is likely to be the most reliable for you. 

Dissolvable fish feeders cannot be programmed as precisely as digital fish feeders, but if you only need a temporary fix for a few days, or you don’t have a big budget, then these could be a more affordable option for you in the short term. 

However, remember to consider the ingredients in a dissolvable feeder and your needs will vary depending on whether you have tropical fish or cold-water fish. 

Pond life will need a much bigger fish feeder, as they require feeding on a different schedule to that of tank fish. Make sure you opt for a feeder that is energy-efficient and has a long power life to make it worth your while in terms of maintenance. 

If your fish like a certain type of food such as flakes, pellets or sticks, make sure that your chosen fish feeder is compatible with that type of food. Some of the best fish feeders will allow you to mix and match all types of fish food so that you can offer variety to your pets. 

And finally, check that a fish feeder is suitable for the size of your tank and that it will be easy for you to fit and program, as the point of a feeder is to make it less work for you, after all.
