Aquarium Care: The Gold Nugget Plec known as L081 is found only in the Rio Xingu, south of Altamira. This L-number is thought to represent up to 3 very similar small-spotted golden nugget plecos, which can be challenging to maintain in the home aquarium. L081 was not included in the formal description of the similar, but larger-spotted fish, Baryancistrus xanthellus, previously represented by the L-numbers L018, L085, and L177. The aquarium should be mature, with a soft sand substrate and various pieces of smooth rockwork and bogwood arranged to create lots of shady caves and crevices. Filtration should be efficient with areas of moderate water movement and a decent level of oxygenation. These large bottom-dwellers require warmer than average water temperatures, and will not do well below 25 °C. Unless the aquarium is of vast proportions and provides a plethora of visual barriers, it is best to keep only one per tank, as these fish can be fiercely territorial with conspecifics and other bottom dwellers that occupy the same niche; indeed, it is not unknown for mature specimens to harass and kill other Golden Nuggets and similar species when kept in slightly cramped quarters, so choose tankmates cautiously and observe carefully. Companions should ideally occupy the middle and upper levels, be reasonably peaceful, and be able to thrive in warm, soft water with areas of decent current - some of the medium sized characins or rheophilic cichlids are an excellent choice. Although these fish prefer a diet high in vegetable matter, they will not make any real impact on nuisance algae and must be offered a varied diet (see below). When they are actively grazing, they are actually searching for their natural food source - aufwuchs - which is a type of algae biofilm that contains small invertebrate life. Robust aquarium plants are rarely eaten, but larger fish may uproot them in their ongoing search for food items. Ensure that regular partial water changes are carried out as these catfish produce a fair amount of waste and will not tolerate an elevated nitrate level. Recommended for mature aquaria and experienced aquarists only.

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 £32 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.
