Weird Betta behavior?

[revdon64]

I have three corys, two black loaches, a rubber-lipped pleco, six giant danios, 5 nerite snails, and another male betta in my 35gal tank and no issues whatsoever. What I'm getting here is that the real issue may just be the size of the tank and the individual personality of the fish. Thanks for all the input friends. I will try to put a screen on the outflow of the filter, and seriously consider moving the corys.

You have 2 male betta in the same tank ?

No wonder why one is trying go upstream trough the filter.

No, I know better than that. Maybe I was unclear. I have two different tanks in two different locations. A 35gal tank at home and a 5gal tank in my office. I have a male betta in each tank. In the 5 at work, where he's getting in the filter box, I also have two corys and a mystery snail. My other betta, in the 35gal tank at home, has lots of company and he's perfectly fine.

Ok, I thought you where talking about the problem tank.

A little update about the betta getting in the filter box. Some have suggested that he might be stressed by having company in the tank. Thing is, he's built a fairly large bubble nest. Again, I'm no betta pro, but I find it hard to believe that he'd display mating behaviors while being stressed by other fish in the tank with him. I also added a couple of "betta hammocks" (fake leaves suction cupped to inside of tank) on the side nearest the filter box, and he seems to be going in the filter less often. Just a random thought I guess.

Well, as long as he can get in and out without problems.

But it's still strange that a filter would have such a configuration that would permit this.

This is the product image from the Petsmart website. You can see how the whole filter box is inside the tank with the outflow lip below the water level. I agree, it's strange.
