Silverwolf Posted December 28, 2009 Report Share Posted December 28, 2009 How do you tell the sex of Black ghost knife fish? I have 2 and they have started dancing round each other need to know if I should be moving all the other fish from the tank or seperating these two to keep the peace abit.

douwe Posted December 28, 2009 Report Share Posted December 28, 2009 From aqua-fish.net Sexing There is no way to determine the sex of this fish just by looking at it. couple of other side say the same one even mentioned that it can change gender if appropriate, so you might have a couple there But they are/can be aggressive to other tank members, I can imagine that will be worse while spawning Quote Link to comment Share on other sites More sharing options...

phoenix44 Posted December 28, 2009 Report Share Posted December 28, 2009 it is pretty normal for them to zap each other, and "dance" circles around each other. keep an eye out for torn fins. I have housed more than 2 together, and they were awesome, and I didn't have any problems at all. Quote Link to comment Share on other sites More sharing options...
Silverwolf Posted December 28, 2009 Author Report Share Posted December 28, 2009 these guys have been happy together for months with the only occassional hissy fit nothing like this tho Quote Link to comment Share on other sites More sharing options...
Adrienne Posted December 28, 2009 Report Share Posted December 28, 2009 could be the change in weather i.e. low pressure system approaching as fish are sensitive to this. I know my male fighters started blowing nests 2 -3 days ago so I knew before it was forecast that there was a colder front coming. Quote Link to comment Share on other sites More sharing options...
