my knife fish i not eating

  • We are currently upgrading MFK. thanks! -neo
First they seemed stressed. Too much light and other fish and not enough hiding spots. They won't stave themselves so they will eat when they want to. They can go weeks without food. It is possible that the goldfish out compete the knifefish for food. And the food that goldfish should be getting isn't the same as the food for knifefish. I'd give those knifefish their own 75 gallon tank If I were you.
 
I wanted a knifefish in my future, but I've read that a lot of the other fish I like will out compete them.

Don't knifefish have an electric sense (probably like the lateral line) that lets them find food in the dark? Maybe it will eat with the lights off?


Also, check your water parameters. Some species are more sensitive to worsening water conditions and one of the early signs is low or no appetite.

South American have electric sense, but not any of the Notopteridea (all clown knife species, ABK, etc) ABK may have them but I don't think so. My ABK aren't very aggressive eaters, but if need be they will eat more aggressive. When my senegal bichir was around, he would eat all the food if the ABK didn't hurry up, so they were very aggressive eaters then, but now they are mellow. They also prefer to eat in the dark.
 
I agree with the idea of frozen bloodworms or any other nutrient rich natural food. Turn the light off in the tank (lights are for us, not our fish in most cases) and if the tank is in a heavily trafficked are of your home, throw a blanket over it for a few days.
 
bloodworms are nutritionally worthless or were those blackworms. Either way, there are too many fish, too much light, and not enough hiding places for them to feel secure.
