Under normal circumstances, it is best not to mix goldfish with other fish. They excrete higher amounts of ammonia, and it is harsh on the other fish in the tank.
No, goldfish are best with goldfish. In addition, tilapia have different needs and are quite likely to be aggressive towards the goldfish.
Bettas and goldfish cannot live together. The bettas will be aggressive towards the goldfish because of its flowing fins. Also a betta lives in tropical waters, 75-78 degrees. while a goldfish is coldwater 68-70 degrees.
yes, dragonfish can live with any other docile, non-aggressive fish.
yes
No. Goldfish are freshwater fish and tropical starfish are saltwater fish.
The only issue I've heard about concerning housing goldfish together is any big difference in body shape or size. Bigger goldfish might be more aggressive towards smaller goldfish. Also, the more streamlined breeds (koi, comet, etc.) might have an easier time snatching up food, leaving little behind for the pudgier, slower fish (fantail, ryukin, etc.).
Goldfish and cichlids have different care requirements and temperaments, so they may not live peacefully together in the same aquarium. It is generally not recommended to keep them together.
The best thing to do is ask the shopkeeper in the fish shop and find out first but goldfish go together with no problems if you are lucky because some goldfish can't live together. http://en.wikipedia.org/wiki/Goldfish
Yes. They are very social fish and prefer to live in groups rather than alone. If you're planning on getting a goldfish, please get at least two so that each one has a friend to swim around with!
The number of goldfish that can live together in a single tank depends on the size of the tank and the type of goldfish. In general, it is recommended to have 20 gallons of water per goldfish to ensure they have enough space to swim and thrive. It is best to research the specific needs of the type of goldfish you have and consult with a pet store or veterinarian for guidance on the appropriate number for your tank.
Angel fish are semi aggressive fish. They may have a tendancy to pick on the gold fish. Also, angelfish need tropical warm water to survive. Gold fish like cold water. I would not put them together. If the Angel is big enough it will eat your goldfish.
no turtles will eat any fish they can catch
