my black ghost died last night beacuase of power outage. i was so depressed cause i never thought that this would happen, when i got home it was too late. i already saw my feather fin catfish sucking at my BGK's body.
sorry for your loss, just wondering if having a sponge type filter inside the tank has any advantage over a cannister or sump, the idea being some bacteria is in contact with tank water. not sure if he died from lack of o2 or nitrites again sorry for your loss
