Angelfish are mainly insectivorous and carnivorous. Goldfish are mainly omnivorous and vegetarian. So you can see that their dietry requirements are different. The reason fish food manufacturers have gone to the trouble to develop and manufacture goldfish food as a separate product from other fish foods would indicate that there is a difference in their dietry requirements. So the answer is No! It is not OK.
Goldfish are like people. They are omnivorous and need most categories of foodstuffs. So yes algae is good (like vegies) for them but they also need proteins and carbs. The better commercial goldfish foods are OK as a basic diet but are all lacking in something. The best way I know of to improve a goldfishes diet is to feed them earthworms at least once weekly.
The pennine packed wood flakes are okay to use with the hamsters.
Yes. It should be fine. I have 2 regular goldfish living with a bubble eye goldfish and to fancy fantail goldfish, so I think it will be okay.
Only if they are white cloud minnows.
yes you can hre is a list okay for adding to the tank: Dwarf Angelfish, Large Angelfish, Anthias, Basslets, Blennies, Boxfish, Clownfish, Goatfish, Gobies, Hawkfish, Hogfish, Parrotfish, Pseudochromis, Puffers, Tangs & Surgeons and Wrasse.
no because the oil on ur hand can kill the fish
Well, it depends. If the one that does not like to eat died then maybe he did not have enough food. If the one that likes to eat died then maybe he had to much food. Just suggesting.
not my dog
No! It is poisonous to them
no
Bettas are. Goldfish really should have an aquarium if you want them to live.
Absolutely not. One fancy goldfish requires 20 gallons on it's own, and a singletail goldfish requires 35 to 40 gallons alone with the exception of Koi which need a large pond.
