If you are using the feeder fish to feed other fish with then I would toss them right away. If you plan on keeping them a while then I would treat your tank with fungus treatment or parasite treatment. More then likely they have one or the other. I would not let any of your more expensive fish eat them and take the risk of losing your bigger fish over a 10c fish. I got some feeders today and when I got home I noticed they all had bumps either on them or inside them and the feeders are for my big oscar and flowerhorn fish and i took the fish back because i wasn't about to risk losing my other fish. Good Luck
Fish are kosher if they have fins and scales. There is no prohibition against eating bottom feeding fish so long as they meet the fins and scales requirement.
No, the Swai Fish is not a bottom feeder fish, but they do have a vegetarian diet.
a goldfish is a feeder fish. I kind of disagree with the answer above. Yes, goldfish CAN be feeder fish, but they aren't necessarily feeder fish. Feeder fish are really fish that are rather small and are fed to other animals, and that are for some reason thought as not being as precious as other "pet" fish. So a feeder fish and a pet fish are two different kinds of fish, really. Not all goldfish are feeder fish. There are expensive goldfish, more than 10 dollars per fish! Then there are those goldfish breeded to be eaten that are sold as 75 cents per fish. So there are "pet" goldfish and "feeder" goldfish. So, a goldfish is not necessarily a feeder fish.
