    See the food and feeding section above for information on what you can feed these guys. Feeders are not recommended unless you quarantine them for a couple of weeks because they can introduce disease into the tank.

    As an adult that would really be too small, your dimensions are about a 35 gallon tank and they should have a minimum of 55 gallons. Also the adult can be about 12' in length, so it wouldn't offer much room for it to navigate.

    Ok,it can live in there until it's about 6 inches and then i'll move it to a 55.

    Update: I decided to get 2,i had them in my 35 until i found my 45... was really a 55.... so... then i moved them.(a few weeks apart,i coulden't catch one).Tip:if you want to SEE your ABKF during the day then you need to stand VERY still so he won't dart away in fright (it helps if you've just fed them).

Can i keep a Panther Crab in a 55 gallon aquarium with: 2 African Brown Knife Fish (4 inches),6 Weather Loaches (3-5 inches),1 Plecostomus (3 inches),and 2 Spotted Raphael Catfish?

    Well, Panther Crabs get up to about 3'  in size and are omnivores. They view any fish, as well as shrimp and crayfish as potential food items. They like scavenging at night and are known for attacking slow and big fish. Because the African Brown Knife, as well as the Pleco and the Raphael Catfish are all bottom dwellers, they will be hanging out in the same area as the crab and so I would be a bit concerned with this mix.

I have 2 knife fish (temporarily) in a 35 gallon,heavily planted tank.They will eat Hikari Massinvore Sinking Pellets,and when they are older (possibly) feeder fish.They are very peaceful and enjoy one another's company.They are a scaleless fish and should only have half the normal medication used for other fish.

I've had an African Knifefish (Brown?) for about six months, except when I'm cleaning the tank, I've never seen it during the day.  Sometimes I'll come into the room after dark and see it swimming around the tank. It appears to be in good health, the tank is well planted withmany binding places.  I understand they tend to be nocturnal, but are there lights I can use to draw them out, and view them?

    You can use a red light bulb to see them when it's dark as they don't see the light. These bulbs are usually sold in the reptile section of a pet store as a nighttime bulb, some reptiles only get active at night too.

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.

    Check amonia levels!  Fish will itch to feel better when amonia spikes.
  • asish timilsina - 2012-12-31
    How do I check for amonia levels this is my first time so plz help me
  • Jeremy Roche - 2013-01-01
    You can either go to the pet store and get test strips or you can just bring a sample of the water you bought the fish from and ask them to test it.  Ask them to test all levels not just amonia.  I would also have them walk you through it so you can do this at home when needed.

I am going to get 1 African knife fish soon,i believe it is about 2 or 3inch long, will a 20 gallon tank be fine for a few months? since it takes years to grown for them.Also when he is at 3 inch is it okay for them to eat feeder fish smaller than them? ive seen some pretty small ones at petsmart. Please if any one could help me, much appreciation.

    For a few months it will be fine, but remember these fish can be very sensitive to tank changes.  They can eat small feeders but make sure they are quaranteened to make sure you do not add disease to your tank.
