The term cognition is often incorrectly used to mean cognitive abilities or cognitive skills..
The best water temperature for betta fish is around 74-78 Fahrenheit, or 23-25 Celsius. Your betta will generally be fine if the water temperature is slightly out of this range (72-80 F), but 74-78 is what their natural habitat of rice paddies in Thailand and other southeast asian countries contains.lightly warmer water temperature for Betta fish (80-82 F) can be used if your betta is sick and needs to be quarantined or separated from other fish while he is being treated with medication.
If your fish is not that old then my advice is to look after it properly by following the rules which are.:- 1 inch oâ¦f fish needs at least 1 gallon of water (a Betta is a 3 inch fish and needs at least 3 gallons). :- Every tank needs a permanently running cycled filter.
