hi, my boyfriend got a new gohst knife fish a few weeks ago but the otehr day we came home and it was having some sort of fit, its mouth was wide open and it was...fitting...for lack of a better word, it then died a few seconds after this. can anyone tell me why this happened as i'm baffled! the water in the tank is perfect and all levels, measures, reading are okay so im quite confused to what happened to his poor knife fish :S

How big is the tank? Other fish in the tank? How old? What exactly are these levels and are you testing with a strip or liquid test kit?

Hi tess
sorry about your fish
gn are super sensitive to water conditiones and it sounds like ammonia ..you say the water was fine but how old was the tank and how was it cycled? what test kit do you use? they really require established tanks that are 6 months old or even more...they also are blind and sensitive to lighting and need dark places to hide...again im sorry for your loss
