The home of the Gold Nugget L18 (also known as the Orange Hemorrhagic Catfish) is Brazil. The freshwater fish lives in fast-flowing and oxygen-rich waters such as the Rio Xingu, Rio Iriri and Rio Pará. Nothing more is known about the life expectancy of Gold Nugget L18. The fish is not suitable for beginners.
What makes Gold Nugget L18 special?
A group formation only exists in younger specimens. Adult specimens are mostly solitary. The fish can grow up to 12-20 cm. This requires large aquariums for successful keeping. The fish are peaceful, therefore they are also suitable for community aquaria. They can easily be socialized with other fish, e.g. red neon tetras, angelfish or bearfish. Disputes within the same species, however, are pre-programmed. Adult specimens tend to be aggressive towards their conspecifics.
The appearance of Gold Nugget L18
The physique is massive, the body colour black sometimes dark brown. The whole body, also head and fins are covered with light yellow or orange spots. The body including belly is completely armoured, the mouth is covered with numerous teeth. In short, a well-fortified fellow.
An external distinction is difficult. However, adult males have a broader and longer head than females and have longer pectoral fin spines and larger ventral fins.
Water values for Gold Nugget L18
The fish love soft and slightly acidic water. The temperature in the tank should not fall below 28°, because then the catfish become susceptible to diseases. The following water values can be taken as reference values:
- pH value: 5.5 – 7.8
- Total hardness: under 10° dGH
- Carbonate hardness: 0-6 KH
- Temperature: 28° C – 33° C
Food and nutrition for Gold Nugget L18
In the wild, the fish are specialized growth eaters, which means that they prefer predominantly vegetable food. The diet should include green and dry food, algae growth, vegetables (potatoes, cucumber, peppers, spinach, salad) and occasionally also frozen food. However, they also like to accept live food such as red mosquito larvae, Artemia and other insect larvae. The fish should preferably be fed several times a day.
The ideal aquarium for Gold Nugget L18
The basin with an edge length of at least 120- 150 cm should have many hiding places like clay tubes, slate caves, stones and roots. Since the fish like to rasp, there should also be plenty of soft root wood. Water plants, with the exception of some floating plants, are often eaten. The bottom of the tank must not be covered with sharp-edged gravel, as the catfish can injure themselves when digging through the bottom.
This species requires sufficient water movement or flow in the pool and clear, oxygen-rich water. The Gold Nugget L18 is extremely sensitive to increased nitrite and nitrate levels in the water. A weekly water change is therefore strongly recommended. In the following the most important keeping conditions in short form:
- Public pool
- Keeping in pairs or small groups
- clear, oxygen-rich water with current
- Warm water temperature around 28 °C
- Regular addition of fresh water
- Root and cave hiding places
- Green and dried fodder (also live fodder)
Features of Gold Nugget L18
If Gold Nugget L18 is associated with other fishes and these are treated with copper-containing medicines such as “malachite green” in case of diseases, one should not be surprised if the catfish stock is dwindling. Copper-containing medicines, can lead to the death of the catfish. Copper-containing slug or algae killers have the same effect.
