    Sounds like the common disease known in it's short form as 'ick'. You can get medication at any pet store. All medication is different, so you'd want to read it very carefully. There are ick guards you can use, too. But you don't want to use those unless you have to. Keep the water clean and the fish fed, as well as unstressed. Big enough tank for what you have. It'll cut the risk down

    If you have a tank full of fish and even if only one fish gets spots that look like grains of salt you probably have ick. To cure ick turn up the heat to at least 86% the ick will fall off the fish ,but they are alive now to kill the ick dose tank heavly with salt tha will kill the ick await a few days and vacum the bottom and do a water change.

Hi, We have had an African Knife fish for around 15, 16, or 17 years or maybe longer. He has been alone for several years (he killed off all tank mates years ago). He is in a 70 gallon and around 12 inches and has seemed fine living this way all along. He mostly eats blood worms and occasionally gets small live feeder goldfish or rosy reds. Recently, (within a day or so after he was fed a treat of feeder goldfish) he can't straighten himself out when he sits or swims. He is like in an extreme 'U' shape all the time. He still eats and otherwise healthy looking. He also has became extremely shy. He was so beautiful before this. Not sure if it is old age or if something else is going on. Anyone out there know??

    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.
  • Knife Fish Lover - 2014-10-02
    Ok,it can live in there until it's about 6 inches and then i'll move it to a 55.
  • Knife Fish Lover - 2014-10-30
    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.
