Linda - 2013-07-12
I have a tank that is 25 gallons, I have 4 BGK in this tank, I love this type of fish and decided to have only this fish. First of all I introduced them to the tank all at once! (all 4) the only other thing in this tank is gravel and 2 ghost houses, (no plants at all) I do have a dual light on this tank however I have disconnected the bright light and only use the black light. I only explain this because everyone has told me that my tank was too small, and that I could only have a small BGK in this tank. I simply love this fish and find them quite hardy in raising so I decided to try and have only this type of fish. During purchasing I made absolute certain to get them all the same size. (rather large) happy to say that all is well! A little chasing, which is fun to watch, but no fighting what so ever. I only feed them frozen blood worms, at first twice a day, but now I feed them only once a day. Is this a miracle or what?! This is contrary to everything that I have been told and read about them

    Hey Linda, this is my very same story. I have always had 3 in my tank, which is 25 gallons. which everyone says is small.They are now 2 yrs old and I have had no problems with them being aggressive, except for a bit of chasing. I feed them only bloodworms, and have also disconnected the brighter light, and have 2 clear tubes in the tank with white gravel nothing else is in the tank.I feed them a cube of bloodworns every other day.I think that they too have their own personalities, but I would never incorporate smaller fish, that said any larger fish will bully a smaller one.

My boyfriend's nephew told him about an aquarium abandoned in the garage of a vacant house and living w/o electricity for an unknown period of time. In it were the Clown Knife, 2 clear Indian glass fish, a tropical black catfish, a Gobie(sp?) and some nearly see-through rod-like flat nose one that had a strange, flat head. The last 2 died w/in a week or two, but the rest are fine, despite our learning as we went. We had to separate the Clown Knife since the catfish became aggressive toward her and she towards the glass fish. Now she lives alone in a 55 gal. having gone from 4' to approx. 9-10' already. We still don't really know how much to feed her and worry when she scoops up a big mouthful of jagged rocks and spits them out when foraging, so we began giving feeder fish every other day or so along with about 1/2 a thimble of slow-sinking food daily supplemented by my daily dig for yard worms to satisfy her huge appetite. Percocet says not to feed her more than her eye size but that seems unfair due to her size. Any advice? I'm proud that she's so happy and relaxed now (and demanding)! She has personality, too rubbing her nose up and down on the glass like a dolphin frantically when we approach as if anticipating another fish to munch. We've got an underwater fan to keep food from settling into the rock substrate and 2 filters including a UV. She loves her rock 'castle' and will chase/nip any tool used to stir up the rocks inside. Very territorial, indeed! She likes me to get close to the glass to study my eyes and mouth when I talk. If I move away, she follows me. She swims around fast, making fast turns to get our attention and relaxes once she has it. If she fails, she goes into hiding. Is there anything else we can feed to ensure a good diet? I don't feel right giving her live fish, although her activity-level has risen exponentially as a result. My backyard has even become a daily dig site for worms - of which she has about 2-3/day.

    A Black Ghost Knife can get aggressive with its own or similar species, possibly like those nice flowing fins of the angel! Making sure the tank isn't too small, these guys reach 20' in length, and that there are plenty of hiding placed all around the tank can help.

I have a 5 inch African brown knife fish in 36 gallon bow front. He is living with 3 agassizi Cory cats and a redtail shark. At the local fish store I was told sharks would be ok but somebody on another site said the shark isn't a good idea at all. I need some help. So far they have been getting along just fine but I'm worried I like all my fish in that tank and don't want them harmed.. Plz help

    You'll have to keep an eye out. When the Red Tail Sharks are young they tend to hide and be subdued, but as these fish mature they are known to get aggressive and territorial issues can ensue. But whether you'll have a problem or not remains to be seen. They tend to be most aggressive to others of their same species.

    Knife fish tend to stay on the bottom of the tank.  It is where they frrl most protected and secure.

    I also have a ghost knife fish and a brown knife fish. I found out that the smaller one the brown knife fish was picking on it. They both give it a slight electrical shock which might bother them. What size is your tank? The more room and hiding places the better.

I once saw a type of aquarium fish in a pet store, which I have never seen again. They looked like beautiful black feathers and they were almost vertical whilst swimming. I've tried to look them up everywhere but no luck so far. If anyone can satisfy my curiosity, I would be grateful.

Are Rams compatible with Heckel Discus, Altum (wild) Angelfish, and Black Ghost Knifefish? How about with Silver Dollars?

    The Knifefish needs a minimum of a 100 gallon tank on his own. They are beautiful but they get huge and he will most likely eat the others.
  • cody - 2013-02-24
    The angel fish isn't recommended but you may try with a knife fish all depends on you tank size to oh and for the discus. Alot of people may tell you to keep them in a single species tank and they need different water phlevels in their tank.

    this all happend over night
  • Clarice Brough - 2013-05-14
    That is very fast, it might be a tankmate is biting him. I'd suggest you watch the tank closely to see if you have a culprit in there that is being aggressive as well.
  • kye turnbull - 2013-05-15
    Pprobably the tandanus! It's always biting fins when its water is low quality (that is one of the reasons I can tell when I need a water change).
