The Siamese algae-eater, also known as the Siamese flying fox or SAE, is, as the name suggests, a fantastic algae-eating addition to moderately sized mature aquaria.
This species is best maintained either singly or in groups of 5 or more of its own kind. Smaller sized groups may result in territorial squabbling. Not only do these fish have a striking appearance, but they will enjoy browsing on many types of nuisance algae, including hair or black-brush algae which most other fish will not touch. As detailed below, the diet must be supplemented with other foods including a good vegetable component. The aquarium itself must be long in order to give these active fish adequate swimming space. The tank should have tight fitting coverslides as this species is known to jump. The water should be well-filtered and a good flow rate provided in order to simulate the clear fast-flowing highly-oxygenated streams this fish originates from. Most plants can be kept safely with this species, so the tank can be well planted along the sides and back. If plants do appear to start being eaten then it is likely to be down to one of three things: Firstly, ensure that your fish have been correctly identified. Secondly, make sure that your fish are receiving a good amount of vegetable matter in their diet. And thirdly, check that the plant munching is not being carried out by another species within the same aquarium. Siamese algae-eaters will be seen browsing on the leaves of plants, but this is for algae removal purposes only, and they will not usually consume or damage the leaves themselves. A smooth sand substrate, bogwood and flat stones/cobbles will all help to create that river bed effect. Strong lighting should be used to encourage algae and which will also promote good plant growth. As these fish are of a peaceful disposition, they make great companions for many other fish, such as barbs, Rasboras, loaches, rainbowfish, and some of the larger tetra species. However, it is best to avoid close relatives/similar looking species (discussed below in more detail) and members of the Epalzeorhynchus genus (e.g. Ruby or Red Tailed Black Sharks). It is also worth bearing in mind that their active and sudden darting behaviour may alarm shy or nervous fish species.

Terms and Conditions

Please read the following before you place an order.

Shipping Policy

We ship our fish with DX, the only courier in the United Kingdom who are licensed to ship fish and other livestock by the Department for Environment, Food & Rural Affairs.

We can guarantee next-day delivery for £30 between Monday and Thursday for orders placed before 1pm and for boxes up to 25kg.

We are able to ship on Friday for a Saturday arrival, but this service will cost £45.

Please note that we will not send a fish that day if overnight temperatures are due to be lower than 6 degrees Celsius.

Some of the fish we stock can be sexed and are sold in a pair of 1 male and 1 female. Please bear in mind, however, that we attempt to match them correctly to the best of our anatomic knowledge but there can be some mistakes, as it is not always guaranteed that the fish will be oppositely sexed.

All our fish are packed in double thickness bags for their safety and security.

The bags are then packed into a polystyrene box with a 40h heat pack and a cardboard outer.

After a shipping date is agreed upon, it is the responsibility of the buyer to be at home when the package arrives.

Once the fish arrive it is your responsibility to acclimatise and then quarantine them using the dripping method. All fish leave our care in good health.

International Shipping

On account of stringent regulations and certificates surrounding the shipping of live fish reintroduced following the United Kingdom’s (UK) exit from the European Union (EU) in 2016, Aquarium-Fish Ltd are no longer able to ship to the EU.

However, we are able to ship anywhere else in the world. Please get in touch if you reside outside the UK and are interested in making a purchase to discuss shipping costs and times.



Dead on Arrival (DOA)

Policy In the unfortunate but unlikely event of your livestock arriving dead we offer a fairly standard common-sense DOA policy, standard for the tropical fishkeeping hobby.

In the event that a fish is DOA, you should contact us within 2 hours of arrival. Failure to meet this timeline will void the warranty with no exceptions.

When contacting us following a DOA, please ensure you send us a video and 3 photos of the fish in the unopened sealed bag it was originally packaged in.

Please take the time to ensure that you send us clear photos. Following a DOA, we will apply the credit of the fish (Excluding shipping) towards a future purchase.

If you pay the shipping again then we can discuss sending you a replacement, or hold the total credit for a future purchase.

If you need further clarification on any of above or have any questions about out range of tropical fish for sale, please contact us via the booking form.
