The bubbles at the top of your tank were made by your betta. Bettas breed under bubble nests, and the male puts the eggs in the nest to watch over them. The bubbles basically mean your betta is happy.

Don't worry, that is normal beta behavior. . . It's like a fish nest. It's just something they do.

the bubbles are eggs mine duse that all the time and i asked about it and i was told its just eggs..if you had a nother Beta you could breed them but you can only leave them in the same tank for a few mins and then take them out..if you have a girl Beta dont leave her in the same bowl as your eggs she'll kill them.

Male bettas build bubble nests. If you put a female in they will breed and he will keep the eggs in the bubbles. strange but true.

It's called a bubble net. Male Betta's do this so a female can put her eggs in it. Males will do this even if there is no female in sight.
