Rate of growth for knife fish? Thread starter superman Start date Jul 9, It also has a very small dorsal fin. Their overall body color is a silvery gray. Their most distinguishing characteristic is a variable pattern of large spots above the base of the anal fin. However, it seems that no two patterns are exactly alike. They may have no spots at all, and sometimes you may find one with two rows of smaller spots.
The specimen pictured above is the albino color form. Fish Keeping Difficulty Clown Knife Fish are not suggested for beginners but rather for an aquarist with some fish keeping experience.
That cute little 3 inch fish can grow to over 3 feet long, but in an aquarium 10 - 20 inches is usually the maximum size. If you plan on keeping one for a long time in good condition, be prepared to setup a gallon tank. Juveniles can be sensitive to water conditions when they are smaller than 9 or 10 inches. Many young fish die soon after purchase normally due to shock or unsuitable tank and water conditions. They are very hardy fish once they reach a larger size. Like most Knife fish they are extremely shy and are sometimes hard to get to eat when introduced to a new tank.
In the wild they are predatory animals, primarily piscivores, which means they mostly eat fish. In the Aquarium they prefer to eat fresh foods such as worms or small fish, but it is a good idea to do your best to condition them to eat sinking pellets or some other dried food of substance.
This will make feeding them much easier and less costly. When shopping for a Clown Knife, avoid fish that are under 3 inches or over 6 inches. The smaller ones are relatively delicate and the larger ones can be harder to get feeding. Aquarium Care This fish is scaleless and very sensitive to water condition changes as with most scaleless fish.
A high quality filter is a must! Water condition tests should also be done weekly to make sure levels are not spiking. Aquarium Setup Clown Knifefish will spend most of their time in the middle or near the bottom of they tank, but they may occasionally go to the surface to grab a gulp of air or a meal. This fish can reach an enormous size even in the home aquarium. They can be comfortable in a 55 gallon tank until they reach around 10", but for the long term you will need a tank that is gallons or more, and bigger is always better.
Use a high quality filter and provide a moderate water current. A UV sterilizer is a smart thing to incorporate into your tank as these fish are very sensitive to medications. The UV sterilizer will kill many diseases. In the wild they inhabit slow moving rivers and lakes in many areas of Asia, so do well in tanks set up similar to this type of environment. Due to their nocturnal nature they need a place to hide during the day.
A piece of pipe or a cave where they can get away from the light works great. Without this, they can become stressed very easily and will try to fit themselves into any dark space they can find, often causing damage to themselves.
They do better with open swimming space, but they are adept as negotiating obstacles such as plants and piles of rock. They prefer a neutral pH and softer water, but larger fish can adapt to a higher pH and hard water. Provide them with well filtered water, a dimly lit tank and hiding places, and you should have a happy Clown Knife.
Social Behaviors They are generally peaceful but due to their large size, they will eat any tank mates small enough to fit into their large mouths. Don't keep them with large aggressive fish, but large peaceful fish are okay. Sex: Sexual differences Sexual differences are unknown. Difficulty: Must have gigantic aquarium to accommodate 4-foot adult size, otherwise of moderate difficulty, mainly due to feeding problems. Tank Setup: The idea is a single specimen tank. Nocturnal, so caves or similar cover are necessary for the fish to feel secure.
Only very young specimens are compatible with conspecifics; two fish in the same tank will fight ferociously. Generally peaceful with ot. Feeding: Carnivore, often difficult to train to non-living foods. Will eat smaller fish, earthworms and other invertebrates, and sometimes foods such as raw ground turkey or prepared food sticks.
Breeding: Eggs are laid on a usually vertical surface. Males defend the eggs and fry ferociously, even threatening oncoming boats. They are bred commercially in Asia, but usually not in aquaria due to their size. Clown Knives grows pretty fast for me.
