Heater - Betta fish like water temperatures between 78-82ºF/24-27ºC

This is a fun one. Hold a mirror up to your betta – or hold your betta up to another betta – and gauge how he reacts. A healthy betta will quickly puff up in reaction to the “other” fish. Once you remove the threat (or, ahem, mirror), his gills should smoothly retract.

In my previous post, I’ve mentioned a couple of time the aggressive nature of Betta fish.

But whether you consider keeping your betta with one another (highly not recommended) or with other fish species, there are some general rules that apply to most situations.

It actually works out nice for us because our room temperature is around their tropical water temps. Water temperature for these fish should be between 75-82 degrees Fahrenheit. The safest route would be to have a heater on your tank if you think your room temp might lower from that range. Figure on 5 watts of heater power for every gallon of water your tank has. With a small tank, heaters are very cheap and will cost under $5 US dollars usually.

Bettas exhibit many signs of sickness, from lethargy to white spots. Any time you suspect a betta is sick, you should take it away from other fish, so that he doesn't pass his sickness on.

Here’s the photo below (I’ve edited the size of the photo to suit the site’s criteria):This adaptation classifies them as a labyrinth fish. This means they can survive for a small amount of time outside of water! It is also the reason they are able to survive in lacking water flow for oxygen. However, water quality is always important in fish care. Bettas will have a much better caliber of life if they are in a small, slightly filtered tank instead of a vase.
