Post pictures of your beloved catfish aquaria here. Also good for pictures of your (cat)fish rooms or equipment discussions. If you are posting pictures of identified catfish, please do so in the appropriate husbandry and reproduction forum above.
Black Ghosts seem to be bred commercially in SE Asia and here is a report with photos of eggs and fry from an aquarium spawn but no other information was provided about sex differences and breeding methods. http://www.gnsaquarium.com.au/html/bgk.html
Here is another account and it refers to the females' having a red 'flashing" about the tail. This account is a breeding set up in Ecuador using diverted river water and not a typical aquarium. http://www.aquariacentral.com/forums/sh ... p?t=141565
