Hello,

I was just reading your information about the black ghost, and I would just like to give a small update -
We bred this fish in our tank a couple of years ago, truthfully, we got lucky and we were quite ecstatic to find we had managed. At the time we thought we were the first ever to have bred these fish, but it turned out a guy in Finland had done it before us :)

However, also a tank owner in Queensland, Australia has been able to keep two babies.

Our little guy was found behind the filtration map, as the egg had been sucked in – there he developed without any disturbance, and so was the only survivor.

The male of the original breeding pair died, and the female was given away to another black ghost owner, and we have not had them for a while.

Only weeks ago, we bought ten black ghosts, so hopefully we will manage again. We keep them in 520 liters tank, with sand on one side and gravel on the other. Many roots and rocks, no surface plants, and give them lots of food, preferably red mosquito larvae.
The filtration is very strong, and I reckon we were "lucky" when the egg was sucked in. It could develop undisturbed on the back side of the "back to nature" background, where the other fish never entered.

I am sure there are several others that can now report that they have bred them, but at least I can guarantee you that it has been done :)

    How did you manage to breed ghost knifes? We have one about 8inches long in a 5ft by 2ft community tank. They are my fav fish in the whole world and i would love to breed them =)

Just to clarify.... 1) BG Knifes also have a dorsal fin which is kept lying in a groove on the back 2) the anal and caudal fins are NOT fused 3) THEY ARE NOT SCALELESS

    Check amonia levels!  Fish will itch to feel better when amonia spikes.

    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.

    That tank is maxed out.  The arrowana is going to get huge!  A bottom feeder like the stingray would normally work but with these messy fish it would be extremely difficult to keep the water conditions right for the addition.

    It will do fine in that sized tank!  Just make sure to have adequate filtration.

I have 2 clown knife fish in the same tank, and I am wondering how much longer I'd be able to keep them together; any suggestions?

    How big is your tank?
  • Clarice Brough - 2012-11-26
    These are such cool fish! They aren't really aggressive, but each fish does need its own space to prosper. As it says above, a 55 gallon tank will work fine for until they reach about 10'.  But with two, I think you would want to give them even more room (and ultimately a 200 gallon tank or so).

i bought 2 BGK fish, both about 5 cm (2 inches) they look fine but I am not sure if this is normal. One during the day just lies next to a plant not moving at all. I always think it's dead so I knock on the tank to be sure. I think it's just sleeping or something since it's a nocturnal fish. At night it's very active it swims all over the place but the other BGK stays in a pipe I put in the tank all day an night just swimming in the same place unlike the other one. Are they ok? My tank is 9.25 gallons (35 litres)is that ok? and how long does it take for them to grow to 15 cm(6 inches)?

    They get BIG like 18 to 20 inches in captivity and need a large tank. They are not super active swimmers they need probably a 50 gallon or more.
  • Eryn - 2012-10-29
    10 gallons is not even close to big enough for one of these fish, much less two. They are small now, but they will grow quick (even quicker if they are fed a high protein diet). You need to upgrade to a 50 gallon (minimum), or find a new home for these fish, before they get stressed out and die.

    You will have to set up another tank. It is hard but so worth it.
