Is a heater needed

Is a heater needed in a tank/bowl?

[dramaqueen]

Not necessarily but if the room where the betta is keptt is cold then a heater is definitely needed.

Your tank needs to be at least 75. If it's under that or the temp is constantly changing a heater is a very good idea.

Thanks.
I dont know what I was thinking.... I knew that! : p

You need a heater.

Best MINIMUM temperature I have found is 78F. I have kept all my tanks with bettas around 84F, though.

I'd say if it is less than 75 you need one. My tank usually stays at 74 degrees as of late, but it is getting warmer so it's now around 76. My only worry is that when the middle of summer hits it will reach way above eighty.

My tank stays at a constant 76-77 degrees.

I measured the temp of the vace. And it was 78f.

What do you do when the temp is mid-80s and up?

Is it ok to drop an ice cube in the tank to cool it down? Well, maybe some ice cubes in a plastic baggie, unless the ice cube is made with preconditioned water.

NO dont drop an ice cub into a tank!!!!!!!!

you will shock your fish to death. frozen water in a chunk, it moves around spreading that cold all over the tank.

Bettas are a true tropical fish, where they come from their water temps range from low 70's to upper 80's depending on the depth of the puddle they are stuck in( yes stuck not choice), the monsoon rains elevate water levels and regulate the temps if the water and the fish move out and swim around the new streams and ponds that the rains create. They are territorial but thats out the window when in a bigger environment.

My betta is at a constant 79 degrees due to his tank mates needing a pinpoint temp setting of 79 degrees
