If you have access to a garden you could dig for the goldfishes favourite food which is earthworms. Failing this, small pieces of uncooked beefheart and cooked lean meat (Chicken) will also be eaten as will bits of bread although too much bread is not good for them. I would advise you to get to a pet shop and buy some more goldfish food ASAP.
There are so many varieties (species) of fish called 'aquarium sharks' that it is impossible to answer your question with any accuracy/authority. However I would advise you to feed 'Goldfish Food' to goldfish and look for some other tropical fish food for any other 'tropical fish'.
Tropical fish flakes tend to have more/different contents because they are designed to feed several different species of fish that require a varied diet. Goldfish food is designed for just one species of fish. Since there are both Goldfish food and Tropical food available it is common sense to feed the fish the correct and appropriate foods. The answer therefore is they can and may eat them but they are not the right food for them so eventually the fish will suffer.
No goldfish would prefer to have a lower temperature than any type of tropical fish, however some goldfish can withstand higher temperature if they are slowly acclimated to it! But in the long run goldfish would be happy with other goldfish and tropical fish with tropical fish... there is a reason you don't see the goldfish with the tropical fish in a good aquatic store.
it depens on what type of gold fish u have ( ordinary or fancy ) The simple answer is no. You can not keep tropical fish and coldwater fish (goldfish) successfully for long. Amongst other things, Goldfish run out of oxygen and tend to stress when kept too hot for too long. The metabolism of Tropicals slows down when the water is too cool and their organs simply shut down and the fish die.Tropical fish and goldfish prefer different temperatures; goldfish like to be at around 70F (room temp), whereas tropicals need more in the 78-84F range, and so putting them together can be problematic in that either the goldfish or the tropicals will be outside their normal temperature range, which can lead to stress and disease.
More than often the goldfish will eat the ghost shrimp.:( sad to say.But if you have a big tank where they can run and lots of plants and caves and stuff so they can hide ,I'd say go for it!you might get lucky.
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.
Yes, but not as their main food source. Oats do not provide enough protein, fats, or vitamins, but can be given for 1-2 days if you have just run out of your regular flakes or granules. Do not feed more than the fish can eat in 3-5 minutes: the leftovers will lose flavor and be ignored by your goldies, and then will rot and foul the water in your tank.
If temperature falls, then the goldfish will take fewer breaths because it doesn't need the oxygen to run the functions of the body.
Well the chemicals in the coloring can hurt the goldfish so it is not safe to have food die in a goldfishes tank!:p Hope that helps!
very carefully or just throw some fish at them and run unless its a zoo or aquarium or something then running's not necessary
like most living things walking fish have character. i used to have two of them one would run away from the fish and the other nearly killed itself trying to eat it. the one i have now doesn't pay atention to the fish. so its up to you if you want to put a fish in with it or not :)
You would kill the fish by poluting the water if you added any kind of sauce to the water. The fish will survive a day or two without food until you can get some proper food for it/them.
