300 gallon aquarium with a 50 gallon wet dry and a VERY elaborate water system for which you change out 1000 gallons of water a week your fish of choice are discus which you both keep and breed s?

Answer 1

You seem to have a really good set up. If you are breeding Discus and rearing them what is your problem/question?

My question is I have 2 black ghosts knife fishes living in this tank and I think one is pregnant and I have no idea how to care for or breed them./ Everyone keeps answering me like I am a moron and don't know about fish and I can find very little literature. I was unaware this was so rare. Keeping black ghost knife fish has always been an easy fish for me . I just don't know about breediong.. I have yet to get a strait answer. I keeping being told i shouldn't bother it is a dificult fish ( untrue by the way) or that it is impossible ( they seem to think zI have ponly 1. etc etc. I would really appreciate a strait answer

Thanks

Black Ghost Knife fish (Apteronotus albifrons) come from the same and similar places to the Discus (which I bred commercially) and therefore they will obviously need similar conditions and water parameters. (That is the reason they are regarded as 'hard to keep' they need 'Discus conditions') You can't get a 'straight answer' about breeding the 'B G Knife fish' because there is no evidence that anyone has ever managed to do so. You can rest assured however that they can not get pregnant because they are definitely egg layers rather than livebearers. They also grow to over 20 inches long so they will probably need your large tank just for themselves to breed in. HTH.
