You should have a thermostatically controlled aquarium heater, and a good thermometer to monitor the temperature.
Although they are sold, don't use the type of thermometer that you stick to the glass; that doesn't give you an accurate temperature. Use one that goes in the tank itself.
For tropical fish, I have had the best success with the temperature about 75-78 degrees F.
Yes, a betta is a tropical fish. Tropical fish all have different temperatures at which they do best at, but goldfish are coldwater fish. Coldwater fish come from from a variety of different temperatures as well, so yes there is a temperature difference. You could not keep goldfish and bettas together because of the temperature difference.
no. they are tropical fish.
Platties are tropical fish and they rely on the temperature of the water to keep their metabolism going. If their water gets too cool, their organs will simply shut down and you will have dead fish. Proper temperature for Platties is about 70F
You can definitely do that, but you haven't made it clear that you have cold water in the tank before. If you can keep the water temperature at 72 F, then you can keep both cold water fishes like gold fishes and non-aggressive community tropical fishes like gouramis, platys, mollies, algae eaters etc with gold fish.
It depends on the fish. If its a tropical fish that is accustomed to salt water, you need salt water and you need to keep the water at a warmer than norm temperature. If its just a regular goldfish, freshwater at room temp should do just fine.
The correct temperature for tropical fish is 72 to 80 degrees. I keep mine at a constant 75 degrees with a heater designed for aquariums.
like you keep a tropical water fish only you should provide it cold water instead warm water.
Most fish can live in water temperatures between 50-80°F (10-27°C). However, some species, like tropical fish, can tolerate temperatures as high as 82-86°F (28-30°C) for short periods of time. Overall, it's important to keep water temperatures stable and within the recommended range for the specific species of fish you have.
It depends on what type of tropical fish you are intending to keep; it ranges from 6 (freshwater & discus) to 8.5 (for cichlids).
Aquarium water should never be hot; depending on the type of fish you keep, the temperature will vary.Goldfish for example are best in 75F, but a betta prefers 80F. Do plenty of research about the fish you are considering for your tank before going out & buying anything.
Its probably from the filter you are using, and probably from the natural fish oils.
tropical fish like hard water, with some softness to it, it keeps theyr fins from bunching up and makes them able to swim faster. ( be sure to use a filter to keep the water running)
