I have two knives a gold one 5.5 inches and a regular one about 7.5 inches named Spooky who is 3 months old and already eats small goldfish and he only gets along with my Bleheri snakehead who is also about 6.8 inches but very mean.

I had a pair of clown knifes for a couple of years, I keep them in a 1000lt tank, when they got to about 60cm they started breeding, They had between 250-300 eggs on a log, by the time the eggs hatched there was about 70 babies, not long after they had babies the female knocked the tank lid off then jumped out and died.

I have a clown knife and an awawana in the same tank they both get along pretty well together. I even noticed that the arawana some times rub up against the knife, is that strange? the arawana evens chews the food for the knife so he can eat it. Is there a way to tell the sex if the knife?

This fish is extremely delicate when is young. It seems to be a real challenge to get them to eat any dry food. They prefer small live fish. However, if you are persistent they will accept pellets. But sometimes getting them to this point of starvation can affect their health. Once they accept a particular type of food. They will eat, and eat. This fish grows and grows. It can reach the size of 20 inches. Therefore, this fish are not for the beginner. And they are not suited for the home aquarium. However, If you have a large tank. They are a magnificent specimen. And they make an impressive display for a large fish. From: Dan
When I purchased my clown knife in January of 02 it was 3 to 4 inches in length. Now, 8 months later it is approx 13 inches long. This fish grows fast. It loves frozen beef heart and that is primarily what I have fed him and of course live fish and some dry, sinking foods. A large tank is necessary as the tank size will not keep him from growing.

So I final convinced Big Al’s to sell me a clown Knife. Damm they didn’t want me to have it. I have had a 90 gallon tank on the go for some time now, with intentions on getting clown knife. I have see them when they are bigger then(mine) 3” and look great. I just thought I would post the progress I hope to be having with him/her (not sure how to tell??). I have lots of plants on my tank, and have found that…. need a name???).. the clown knife loves to hide until its dark, I think is cool. I have had the clown knife for a week now and it seems like he is eating a little. I have yet to give him any live food. But I have seen it eat the dried shrimp. Just to let you know, as it stands now I have the clown knife in the 90 gallon tank with: 6 zebra dannios, 1 blue female betta, 2 angle fish, 6 large blue grourami’s , and a far size pleco. I have yet to see him bother any of the other fish.

I had bought a clown knife, the last fish I purchased after I got my 54 gal tank. He is now 7" long and ate my $40.00 albino plecosomous. I was so upset. Now my poor clown loach is missing, without a trace! I guess only the strong survive. But he is my favorite fish of the 3 I have left.(R.I.P.)My little ones.

My spunky little clown knife (5 inches)finally gorped its first goldfish today (so proud). Its tank mates are an Oscar, and a 10 inch common pleco. Adding a silver arowana (5 inch) and going for the 100 gallon tank in 2 months.

From: Daniel
My clown-knife is living great with an oscar, pleco, and arrowana. At first I was worried because he was not eating, fish would swim right in his face and he'd make a halfhearted attempt. Now, I have to keep him from eating all the feeders first. My arrowana is not a good hunter so I have to feed my arrowana crickets since my knife-fish and oscar will eat up all the feeders first. He tends to stay in the corner a lot so he is not the funniest fish to watch. But, like watching him eat. I changed his name from Blade to Hunter because he is so good at catching fish.

From: Gareth
When I first got into fish I had a community tank with shrimp, frogs, neons, tiger barbs and too many to mention other fish. I went to the pet store and there was sign for the clown knifefish saying it was a community fish, so I bought two. That was on the Friday, I had to take them back first thing on the Monday. They ate 18 fish all together and two shrimp. They was eating the fish through the night I tried to slow them down buy getting up late at night to feed them but it was no use. I now have oscars and a electric catfish and none of them are as predatory as this fish. I would like get one again now as I have a larger tank and tank mates for it to live with as they a very pretty fish.
