Bubble Eye Goldfish Need A Little Advice On Heating And With Tropical

[matrix]

Hi all
I have 3 little bubble eyed goldfish. A black and purple one a red and white one and a all black one.
I don't have any heating on in the tank at all and the water is seems pretty cold should i have some heating on in the tank?

Also is it regarded as a sin to put the bubble eyed goldfish in with the my tropical fish ( rio 180 tank) i have?
Reason i ask is that i've heard people of doing this?

Thank you.

the ideal temp for bubble-eyes is 70-74F
The “bubbles" are delicate and are easily damaged.
They will repair themselves in time.
Care should be given to tank decorations and other fish to
prevent damage. They are best kept with other Bubble eye or Celestial eye goldfish.

I would not put them in a tropical tank with other types of fish
