You're sure it's an oscar? Those things are opportunistic predators--basically, they'll eat anything that will fit in their mouths.
Seriously, though, some cichlids don't like to eat guppies for whatever reason. They don't NEED to eat live fish, and a lot of fish experts say not to feed live fish. So...if it won't eat guppies but it will eat chopped beef heart, earthworms, cichlid pellets or whatever else you're feeding him, I would just not put any more guppies in there.
not a chance. you could buy guppies as feeder fish for them though.
I am assuming you mean are guppies a good food for Oscars. Yes they are provided the guppies are free from disease.
Oscars eat about anything, like guppies and small aquarium sharks.
No, guppies are fish.
Oscars are carnivorous fish, so they can spend their entire lives eating insects, fish and other organisms smaller than itself. A Fightn' Fact- However, Goldfish are HORRIBLE feeder fish that contain too much fat. In short, Goldfish will kill your fish over time. Just buy a 5-10 gallon tank for guppies. They cost more upfront, but are less expensive in the long run. They breed rapidly so they re-stock themselves monthly. Guppies (whether pets or food) will save you a lot of money.
If you have an over population of Guppy fish you might consider placing one of its natural predators in the tank for only a short time to reduce the over population : Oscar Fish, Jack Dempsey, Cichlids, or Paradise Fish. this new addition will need to be removed after the desired amount Guppies have been reduced.
No, they will eat them.
The tiger fish would eat the guppies.
Guppies are a type of fish. There are no types of guppies.
Fish that have long, wavy fins should not be put with guppies, because guppies will nibble their long fins. Also, many bigger fish will eat guppies. Keep a separate tank with guppies and a few "cleaner" fish, which do not harm guppies.
Only guppies breed with guppies naturally.
Guppies are omnivores and do OK on normal Tropical fish flakes.
