I have a pair of Wallaceochromis Signatus that have spawned and are now ushering the fry around the tank. There is a C. Leopardus in with them that they keep chasing up to the top of the sponge filter and 5 African glass cats they keep up in the corner.
I've been keeping the light on 24 hrs a day since I expect the cats may get the fry if I let it go dark. It is just a single fluorescent filtering down through a layer of duckweed, so not very bright.
I expect it would be better to give them a period of darkness, but I've done this with a few fish when I thought tank mates would eat fry and haven't seen any issues.
Am I missing anything? Are there studies that show this is a problem?
