i hate to burst your bubble but you cann't have a third eye
your stuffed. aka say bye to your eye!
Yes, of course! They are perfect to live together because they are both slow swimmers, and you won't have to worry about one of them starving because another faster fish got to the food before the bubble fish did. Just make sure that they both have enough room to swim around it, that's about 10 gallons of water each.
If it is looked after properly it should live for around 20 years or so and grow to over 10 inches long.
After numbing the eye with a local anesthesia, the surgeon injects a small gas bubble into the inside of the eye. The bubble presses against the retina, flattening it against the back wall of the eye.
Boom. Eye Gone! O_-
NO.
Goldfish do not have teeth.
Yes. It should be fine. I have 2 regular goldfish living with a bubble eye goldfish and to fancy fantail goldfish, so I think it will be okay.
Get it looked at.
You may be thinking of the phrase "apple of my eye" which means something or someone cherished above others.
