I have a really pretty crowntail beta fish in an approximately 1 gallon fish bowl and I have a question?

Males make a bubble nest when they are ready to breed. The male takes care of the babies that's why males make the nest. You don't have to breed them though and you have to wait till the female has vertical stripes if you choose to breed them. Also Bettas CAN live happily in a 1 gallon bowl.

A$h!

Well, other people have already filled you in on the bubble nest... Male bettas blow bubble nests when they see a female and feel like mating, or when they just want to mark out their territory. It's usually a sign of a healthy and happy betta.

I'm not sure what you mean by a layer of slime. Is it a filmy substance floating on the water surface? If so, it could be from excess proteins due to the breakdown of uneaten food that has rotted in the water. You need not worry about the protein film, but if there is uneaten food in the tank, it's rotting to produce ammonia which is toxic to your fish. Be careful not to overfeed your fish and remove all uneaten food from the water within 10 minutes of feeding.

By the way, for a 1 gallon bowl, you should be changing his water every 3-4 days. One gallon of water accumulates waste pronto. Although one gallon is sufficient if you are diligent about water changes, you would have a lot less work if he was kept in a 5 gallon tank, which would probably only need partial changes every couple of weeks once cycled. You should also have his water heated; bettas are from tropical climates and unsteady or cold temperatures can make them lethargic and susceptible to disease. Junior heaters are available for one gallon tanks; keep his water at a steady 80 degrees and he will be much happier for it.

It is making its nest

The male betta fish make a bubble nest so the female can lay her eggs in it. Most all males do this, whether there is a female near by or not. Its perfectly natural and it shows that your betta is happy

People say that bettas need a nice big tank with a filter and all that jazz, and im all for keeping animals in something that keeps them happy, i never put any of my animals in a tank to small, or a cage, but i do keep my betta fish (i have 2) In their own 1 gallon bowl, they have a little cave they can hide in, and a plant, and i clean their bowls ever 3-4 days, so i think its fine to keep them in a small bowl, just no less than 1 gallon,

and you really dont need to feed them 2wice a day, betta fish dont know when to stop eating and will even eat themselves to death if there is enough food (ive experienced this, their stomach exploded inside them) Just feed them 5-6 pellets a day

and also, make sure you dechlorinate the water if you use tap water, its a cheap liquid that you can get at almost all petstores~and if you do this now, good job, because it seems alot of betta fish owners dont dechlorinate

Well, i hope i could have helped out some

have fun with your betta

When a male betta puts bubbles up at the top of his tank that means he is happy and healthy,because in his native home that would mean he's ready for a female.I don't know what slime would mean but if you're feeding him right and changing his water regularly,then it's probably OK,but if you're not,then something may be wrong.My betta has never had any slime,but slime may be normal,I've never heard of it. My betta doesn't have pellet food,his isn't as big,each morsel is a little bigger than a grain of sand. But I just feed him a couple pinches a day and he seems to be doing fine. As always, have fun with what you're doing,and I'm sure you're betta will too!

Betta fish build bubble nests when they are happy. In nature, they use it as a way to attract mates. Congratulations, it sounds as if your Betta fish is very happy for the time being.

In fact, when I used to have my Betta (RIP), I would keep an eye on him more when there WASN'T a bubble nest. That would mean something is probably wrong... or that something needs improved upon.

However, I am unsure of what you mean by slime. If it simply looks like bubbles, that is normal... but slime? Maybe you should rephrase that to explain what the slime looks like.

Also, upgrading his aquarium like others suggested MIGHT be a good thing to look forward to someday... but it is not necessary. He is fine in a 1 gallon for now. You might, however, want to upgrade to a 5-10 gallon one if you want him to be TRULY happy. The only thing you need to worry about then is to make sure the filter current isn't too strong and that he is the only habitant of the aquarium (I once had a Beta fish live peacefully with 5 tetras but he would chase them occasionally).

Well, Betta fish should never be kept in a fish bowl,they need a tank with maybe a heater, but I think that the slime on the water is probably just a sign that the tank needs to be cleaned again!

yup thats coomon hes just making his nest. i have beta fish two he is 2 years old and he is in 2.5 gallon fish tank. 1 gallon fish tank is o.k. but i would recommend to get a bigger size tank its up to you

ive had that and idk what the heck it is but it didnt turn out to be anything bad for me
