I currently had 2 african knife fish from a few days now. They really skittish at first, but went I added a few fish with them like a ladder loach, they became more regularly seen during the daytime hours, become increase activity. Recently one had the aggressive and occasionally chasing the knife fish.

Is it possible to spawn them? I have a slim and chubby one.

Hi,

I'm Mitchell Romanowski,

A couple of weeks ago I bought a black knife Goast Fish that was about 5 inches and cost about $30.

It's nocturnale\ and doesn't like light, so I made a cave for it to hide in.

When I feed the other fish, it doesn't touch the food because it doesn't want to go into the light to take the food.

A couple of days ago, I tried to hand feed it in the cave and it ate a whole cube of blood worms. The bits that it missed, the clown loaches and yoyo loaches ate.

I feed all fish including the ghost fish, brine shrimp, blood worms and high quality flake food to balance out their diets.

I've got about 15 plants, (small and big), in a large 4ft tank with lots of rock structures.

From Mitchell

I currently own one Clown Knifefish. I got him when he was 3 1/2 inches and in 2 months he had grown to about 6! He is the shyest knife out of the 3 we own, & tends to let them pick on him time to time, even if they're a lot smaller. He is a hardy fish who loves to hide in his hut. He likes hand feeding frozen silver sides, black worms, and also likes hunting minnows. He's growing fast in our 75 gallon. Such a wonderful fish.

Hey guys, I have a knife fish who is very happy in my 55 gallon aquarium w/ many different species. But some of the other fish have started to get aggressive towards the other fish (not my knifefish) due to the high protein I have to feed my knife fish. I usually feed him bloodworms or brine shrimp. Any suggestions how I can feed my knife fish but keep the other fish on lower protein diets?

    Yes use a turkey baster. That's how I feed mine. You just take the rubber squeeze ball end off and drop tje frozen brine or blood worms in the clear plastic part and put the rubber squeeze ball back on and suck up some aquarium water and swift it around to get it to melt and stick it in the aquarium in front of the knife fish or by it and squeeze it to feed them. I do this every time with my blood parrot fish and African brown knife fish and works very well for me.

My knife fish is in a 40gallon tank and I've had it for 4days now. Yesterday it formed this white skin shield over it's eyes. What does that mean? Is it going to die?

    It definitely seems to have some type of illness, although I'm not sure what. You could always try a broad spectrum antibiotic.

    No all you have to do is just keep the water clean and buy a medicine that will help it heal.

    It means your tank is too small and you should dim the lights.

    It might, but what it has is some kind of eye infection, go to a local fish store NOT PETSMART or any big chain store, they mean well but 99.9% of them haven't the faintest idea what they're doing, and it was probably caused by the stress of changing tanks.

I never see my knifefish. He stays hidden at all times! Kind of a disappointment! I only have one. He's in a 55 gal tank w a couple sharks and 4 gouramis and a couple tiger barbs.

    Depending on how long you've had him he might just keep hiding, also tiger barbs are famous for nipping fins, and a knifefish's undulating fin is a big temptation. I have mine in a 75 gallon while at least 6 or 7 hiding places so he's good, and mine will turn right around and bite at whatever bites his tail. They also don't like bright lights much( mostly nocturnal), so try dimming your lights by taking plastic plants, ripping them out of the little roots and letting them float right under your lights and/or giving him more hiding places, they like dark caves, broken/upturned flowerpots or PVC pipe will do, and if all else fails just give him some time and he should come out more often over time.
