Quick Answer: What Is A Good Temperature For Tropical Fish?

Is 82 degrees too hot for tropical fish?

The ideal range for a freshwater tank with most tropical fish is 77 to 83 degrees.

This will make 95 percent of the fish out there very happy.

For a saltwater tank, the range is 76 to 82 degrees.

For the reef aquarium, slightly cooler, at 76 to 78 degrees, is best..

How hot is too hot for tropical fish?

Tropical fish, for example, do best between 75° and 80°F, goldfish and other “cold-water” species prefer temperatures below 70°F, and temperate fish can be found in habitats that overlap tropical and cold-water realms.

Will 82 degrees kill Ich?

At 82, the life cycle of the parasite is sped up, but it won’t be killed. There are enough heat resistant Ich strains out there that I don’t even bother with raising the temperature – I go straight to a medicinal dye. … The parasite has adapted, or warmer water species of Ich have been accidentally introduced.

What temperature is too cold for tropical fish?

Best Temperature It depends on the species, but in general, tropical fish are most healthy in the range of 75-80°F (24-27°C). Cool water fish do better in temperatures below that, usually between 60° and 75°F (15-24°C), but some of them enjoy water well below 70°F, which is not suitable for any tropical fish.

What do I do if my fish tank is too hot?

Float a bag of ice or cold water in the fish tank to gently lower the water temperature. (Take care not to lower the temperature more than 2 or 3 degrees F in a 4-hour period.) Avoid putting ice cubes directly into your aquarium unless you make them with reverse osmosis or dechlorinated water.

Is 30 degrees too hot for tropical fish?

Most tropical fish will live happily in water with a temperature of 24-26C, with some preferring a few degrees either side. In a heat wave lasting a few days, aquarium temperature can rise quickly to over 30C and at this temperature many fish will start to run into trouble.

Will tropical fish survive without a heater?

Tropical fish require a heater in their tank to maintain their water at the appropriate temperature. The general range for tropical aquariums is 75-80 degrees Fahrenheit. Left alone, the aquarium water temperature will eventually match the surrounding air temperature.

What kills the most fish?

Of known causes, fish kills are most frequently caused by pollution from agricultural runoff or biotoxins. Ecological hypoxia (oxygen depletion) is one of the most common natural causes of fish kills. The hypoxic event may be brought on by factors such as algae blooms, droughts, high temperatures and thermal pollution.

Is 86 degrees too hot for tropical fish?

The ideal range for a freshwater tank with most tropical fish is 77 to 83 degrees. This will make 95 percent of the fish out there very happy. For a saltwater tank, the range is 76 to 82 degrees. Now keep in mind that whenever you increase temperatures, you decrease the amount of oxygen available to the fish.

Why do fish die after water change?

Over time the by-products of fish waste, uneaten food particles, dead leaves from plants, etc., alter the chemistry of the water. … When a sudden, large water change occurs, it causes such a drastic shift in the makeup of the water that the fish often cannot tolerate it and they die.

At what temperature does ich die?

The breeding stage of the parasite encysts between the layers of the host skin. When mature, it leaves the fish and produces large numbers of free swimming young. These must find a host within 48 hours (at water temperatures of 75-79°F) or they will die. The life cycle of “Ich” is shown in Figure 1.

Can angelfish live in 70 degree water?

Generally, the temperature limits should be considered to be within a range of 65° to 85°F although 5 degrees can be extended at the upper and lower limits if the time is brief and the aquarium is well aerated and filtered. For ordinary maintenance of angelfish, a temperature of around 75°F could be considered ideal.

Can fish die if the water is too warm?

Warm water causes the biggest issues, typically once temperatures exceed 90°F (32°C). Your fish breathe by drawing oxygen out of the water. … Just one problem – warm water actually holds less oxygen than cooler water. In severe cases, there won’t be enough oxygen to go around, and your fish can suffocate.

Will cold water kill my fish?

Just as salmon are accustomed to cold water temperatures, several Florida fish like tilapia and peacock bass are acclimated to warm water temperatures. So, if we have a cold snap that lowers water temperatures below 55°F, entire populations of these non-native tropical fish will die-off.

How long can a fish stay in a bag?

We’ve all brought home new fish from the pet store in those heavy-duty plastic bags filled with water and air, but have you ever wondered how long fish can survive in a bag? It depends on a host of factors, but in general, fish can easily survive in a bag for about 7 to 9 hours comfortably, and possibly up to two days.

Can you put 2 heaters in a fish tank?

Purchasing two heaters will ensure there will always be a backup heater. It is a small investment to ensure the safety of your fish. Purchasing two lower wattage heaters will keep the temperature stable. … Two heaters means that emergency use in another aquarium is possible.

How many fish can I have in a 10 gallon tank?

The next question is how many small fish can you add to a 10-gallon tank? Initially, aim for around one small fish per gallon of water, adding them in small groups every couple of weeks. Once the aquarium is mature and your skills are honed, you should be able to keep two neon-tetra-size fish per gallon.

How do I know if my fish is too cold for water?

The most common sign of temperature shock is lethargy. Fish are cold-blooded, so unlike mammals who generate their own heat, they can only absorb warmth from the water. When the water is too cold to do this, they’ll often stop moving.
