Is this Normal?

[Worthless]

I have 4 fish in my tank currently, 3 platys (1 male and 2 female) and a Male Betta, My Betta puffs up at any of the platys that get near him or his skull (tank ornament) and chases them, Last night I thought it was Normal for him to be territoral but last night I was watching him and the Male platy didn't run from the Betta and the Betta lunged at him, So what should I do?? I am leaning towards that he will calm down a bit, He has tamed down greatly, Another thing I noticed when the Male platy was chasing the females the Betta jumped right after the Male Platy:O

That happened to my Juju too. All of a sudden he got very aggressive towards my swordtails. So I got him a female betta. Yes, burn me if you'd like. Most people would not recommend doing that. But he was ok after that. He didn't even attack her as much as he did the swordtails. They lived happily together and even had eggs (without fry though.)

Maybe you can get some more plants or something to provide more hiding spaces. Do you have a full tank shot? We'd like to see your tank.

As Requested, here is a picture of my tank, leave some suggestions

Cool, I'd definitely get some more plants and maybe a background.

how big is that tank?

I believe it's a 10g. It was posted on another thread.

Looks bigger than a 10G...
Get more plants to break up the line of sight. He's being territorial sounds like. With more plants it gives the others places to retreat and hide.

BTW, lovely looking betta.

Thank you and yes its a 10g tank, i have box right beside me

Yes. Divide up the area a bit with some taller plants/decor would help make the territorial division better, allow for more hiding areas, and define spaces.

Even a small clay pot upside down does wonders. i just put three in one of my tanks and it helped mellow everyone out. i agree with kissyboots on the background.

i still think the problem is in having the betta in a 10g with 3 other fish. adding plants and hiding spots to create territory and break up lines of sight could help, but it also comes down to having enough room in the first place.
