no
Goldfish may be kept in an uheated fresh-water aquarium. They are considered ill-suited to live in a heated tropical fish tank, as they are used to the greater amount of oxygen in unheated tanks.
A guppie is a tropical fish and should be kept in an aquarium with other tropical fish, a goldfish is kept in a bowl or tank in cold water - the 2 cannot be kept together because of the different in the temperature of the water
Mollys (Poecilia sp.) are usually regarded (and kept as) fresh water fish but they actually come from brackish water originally. With slow and carefull conversion they can be kept in fresh or salt water environments.
Just leave the aquarium at room temperature.
It just needs to be clean I don't know if a goldfish can even live in salt water. I always put the ones I've had in tap water that set out for a day or two I don't know wye it needed to sit out for a couple of days before putting the fish in it but that's how my mom always did it so I figured it was probably for a good reason. I actually had one goldfish that lived for like 4 or 5 years that's a long time for a goldfish. Goldfish need to be kept in fresh water, they are not made to live in salt water. preferably, keep them in spring or kangen water. By the way, you mom left the water out for a day or two to get it to be room temperature. Goldfish need to live in water the temperature of 70-75 degrees Fahrenheit.
Well, the correct answer is no. But when I kept my tank at room temperature, I had no problems.
Goldfish are best kept with other goldfish or similar coldwater species that can tolerate cooler temperatures and shared tank requirements. Good tankmates for goldfish include white cloud mountain minnows, dojo loaches, weather loaches, and rosy barbs. Avoid fish that may outcompete goldfish for food or nip at their fins, such as tropical fish like angelfish or neon tetras.
Goldfish and cichlids should not be kept together in the same tank. Goldfish prefer cooler water temperatures and produce a lot of waste, while cichlids prefer warmer water and are more aggressive. This can lead to stress and potential harm to both species if kept together. It is best to keep them in separate tanks to ensure their well-being.
I do not know of any Algae eaters that can live in cold water . Goldfish are cold water fish. So unless you can find some species of cold water algae eater the answer is no they can not be kept together successfully.
It is reported that they loose colour if kept in a low light situation for a good length of time.
No. They require totally different conditions. Goldfish are cold water fish and should not be kept in water above 70F. Plecostomus sp come from the tropics and should be kept in water above 75F. If you keep them together one or the other will be in conditions that do not suit it so it will probably sicken and die.
increase in size untill it bursts.
