Black Ghost KnifefishBlack Ghost Knife FishFamily: Apteronotidae (Ghost Knife Fishes)
Latest Reader Comment - See More Kyle, Plecos and bottom feeders are included in that... they are bottom feeders and they count as fish. Yeah, it is over crowded with a freaking 10" pleco. J 2010-02-01 The popular Black Ghost Knifefish is readily distinguished from other knife fish by the white and black banded area just in front of tail fin!Black Ghost Knife Fish Contents The Black Ghost Knifefish received its unusual name because of a rumor that some tribes in the Amazon jungle believe that the souls of the dead inhabit this fish. No one can substantiate this information and it may just be a story created by the people collecting the fish, but it's a good story. For good reason, the Black Ghost Knifefish is the most well known species of knifefish in the aquarium industry. One reason for this is that they have been imported for decades. Other reasons include being unusual, interesting and amazingly beautiful. Until a few years ago, all offered for sale were wild caught and had been imported from South America, mainly from Brazil. The good news is that they are now being bred in Indonesia by the thousands, so much of the pressure has been taken off the wild populations. Odds are that if you see an individual of 5 inches or more offered of sale, it was collected in the wild. Specimens smaller than 5 inches were most likely produced in and imported from Indonesia.

Availability: Now that they are being bred in captivity, the Black Ghost Knifefish are available all year long.
Large specimens may command a high price, mainly due to the higher costs of shipping them. Smaller specimens are quite affordable.

| Kyle, your 44 is overcrowded. The 1" per gallon rule doesn't hold true when dealing with large fish - it simply doesn't account for the amount of waste produced.
I agree with Koop. Rehome some of your fish.

| I have a 29 gallon tank with quite an assortment of fish ranging from bettas, sharks, dragon fish, and one ghost knife I call my queen. She is beautiful and seems quite content. although she stays hidden during the day she comes out at night and eats from our hands. She is definitely my favorite!

| My 44 gallon tank is not overcrowded. Firstly most knifefishes never grow 20 inches in aquariums, that twenty inches is based on a wild caught specimen out of the spacious amazon river. Secondly, have you heard of the inch per gallon rule. Every inch of fish needs a gallon of water. Tiger barbs and flying foxes grow three inches long; 6 total, times 3 inches equals 18 inches and a required 18 gallons of water. The 18 inches of the barbs and flying foxes and the 12 inches of firemouths and the 5" knifefish puts me not only under the limit according to the inch per gallon rule; but allows the knifefish to grow to a length of 14" long. Thirdly, knifefish are one of the slowest growing species of freshwater fish in the world. It will take years for my knifefish to even reach 14" in length. By the time he reaches 14", almost everything else in my tank will be dead. That's how long it takes knifefish to grow. I bought mine over two years ago when he was just under three inches long. That is an inch per year growth rate. And when he does get long enough, I have a 200 gallon tank with oscars he can move into. I am just growing him out in my more peaceful tank until he is big enough to live with some oscars with out getting eaten. Lastly, bottom feeders like plecos don't count towards the space required for the tank. Check your facts before criticizing someone who has 25 years of experience with fish.

| I have a 350 gallon tank with a small amount of fish. I have 3 dragon gobies that seem very timid and 3 ghost fish that only come out at night. I'm very fond of this type of fish but am having trouble finding out other types of fish to put in it. My oscars and parrots oddly get along great. I need some suggestions on other fish that will get along to put in my tank.

| I got two black ghost knifes a year ago and they get along fine. I've been feeding them frozen bloodworms and they've started eating out of my hand. They seem to have gotten used to the light, now it looks like they couldn't care less if the lights are on or off, but when I turn off the lights, they immediately rush out of their caves and swim vertically along the top of the water, looking for food. Most awesome fish ever! 2009-09-02 |
