    That is pretty normal for them.  More then likely moves around when no movement in room.

I have bought 2 bgkf and I have a 125 gallon tank. Both fish have died within a day of me buying them. I have 2 red tips a black shark and a rainbow shark. My water always tests fine pH is 7.0. I am confused and disappointed. I don't know what's causing the fish to die. Any help would be nice.

    Could be the place you got them from. How did you acclimate them to the tank? They stress very easy so a slow acclimation is best.

    I allowed the bag to float for 15 minutes and than released them into the tank. They were active and found a hiding place. Next morning they were fine and a couple hrs later they died.

    Try buying them from a different place.

    Maybe cause there was two of them, they couldn't really identify anything cause they were both sending electrical waves that kept intercepting the others.

    I bought my first Black Ghost fish about a month ago from Petsmart and I fell in love, however about 2 weeks later I could not find it in the tank. I have a 150 gallon tank and I looked everywhere in the tank and cold not find it. No remains indicating he was dead. I just recently bought 2 more less than a week ago and they seem fine. You do have to watch the fish you get from Petsmart. I suggest not purchasing anytime from Thursday thru Tuesday as they get a new shipment in on Thursday and therefore you run the risk of disease and the fish being stressed out from the shipment. I experienced 2 bouts of ick from my fish there, before I realized it was best to have a quarantine tank set up for new fish and not to buy fish when they first get them in. I did however by my ghost fish 2 days later only because they don't keep them more than 2 days in stock due to the high demand. Thankfully my 2 have survived for 5 days today. Good luck!!

    Ick is due to stress. All fish carry the ick virus, it's when they are stressed it comes out. It's like a common cold for us. Immune system is down bam we get sick. To blame it on pet stores is ridiculous. It could have been the stress from being transported to your tank,or the stress of being shipped to the store. you should be checking the fish out before you purchase it anyways, never rely on someone else even if they claim to be 'experts.' When medicating you should use half the dosage because they are a scaleless fish they cannot handle a full dose.

    White spot is not carried by all fish! A parasite, ichthyophthirius multifilliis, it comes on plants, fish that have it, gravel or water! It's not in every fish!
  • kye turnbull - 2013-04-04
    Although you are right about the scaleless dosing.

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 :)

    We have a tank (75 gallon) and We had two ghost knife fish... who are very happy with their environment. And at the moment we have 9 offspring of different ages. Its getting to the point where we need to sell some!

    Wow! How lucky you are.. how I wish I could do so too.

    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.
  • 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.

    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).
