I've recently got a pair of goldfish and put them in a bowl. I'm trying to keep them happy by feeding them all the natural thing they eat in the wild (and they are loving it too).

It has been 4 ~ 5 days and things were going fine, until I got them a little bulb to keep them warm and light up the bowl a bit. But, after around 2 hours from the moment I switched the bulb ON, the fish would come to the top, pop their mouth out of the water surface a bit, and gulp air, then they would go down and release bubbles.

Initially, I thought, that due to low oxygen and high impurity rate in the bowl, they are gulping air from the top and immediately changed the water. But, again when I put the bulb back on, they started coming to the top releasing bubbles.

I don't know if they are doing this to get more heat (as it's a bit cold these days here) or they are just feeling good doing this... Please help me as soon as possible... :(

Edit 1:

  • Both of my fish are 2.5 inch (7.5 cm).

  • I change their water every 3 days.

  • When the bulb is removed they discontinue this behaviour.

I just went to the pet store and got an air pump and an air stone and installed them to my fish bowl. I observed that this solved 3 things :-

  • Air bubbles trap some of the dissolved impurities and release them at the surface.

  • Replenishing oxygen level in water by increasing the surface area of water in contact with air.

  • Generating disturbance at water surface, generating little waves, and continuously moving the inside water which most fishes are fond of.

I also observed that my fishes are not struggling to breathe anymore. :D
