My bully of a betta

[The Betta boy]

Let's start at the beginning. I bought this betta to breed with my other betta, Sal. Along with Scarlet, the aforementioned bully, I also bought two glowlight tetras. These tetras were supposed to be for entertainment purposes for Sal. But when I added them to his five gallon tank, he chased them around, even after I fed him early. So I put him in a one gallon tank(which I felt guilty about) and put Scarlet in the five gallon tank with the tetras, as I had no other tanks at the time. Everything seemed normal, fast forward ward the new ten gallon tank and getting two more tetras, to when I bought a used but working condition 55 gallon tank. During a %50 water change, I moved them to the filled put scarcely decorated 55 gallon, which had no other fish. Before I could change them back to the ten gallon, I woke up to one of my tetras away from the others. Upon closer investigation, it, overnight, had lost an eye. Before that, none of my other fish had been hurt except for Scarlet in the failed breeding incident. I called around, and my mom said she'd take Scarlet out because I needed to get ready for school. Fast forward me buying 8 more tetras, 3 of them neon, and all but one glowlight and one neon dying in what I called the 77th hunger games, to now. I bet you guys loved me putting so much backstop in. She is now in the ten gallon with the two surviving tetras, steals their food, chases them around, etc. She also is fat and/or bloated. Do you have any suggestions on how to fix some of these problems? Picture is of Scarlet.

I think your experience is sufficient to resolve yourself to remove the tetras.

The tank would need a much more complicated hardscape, with lots of lush rooted and floating plants to give maximum cover.

If you remove the tetras, it's going to be easier to prevent the betta to become overfed.

Where would I put the tetras?

 

[The Betta boy]

I'm working on redecorating my 55 gallon, they're in my ten gallon, and Sal's in my 5 gallon.

If it's temporary you can use any container big enough for the betta, he'll be mad at you, but will survive.

But, they like to hunt and fight, some are serious piece of work and wont even stand snails.

 

[The Betta boy]

What if I put the female or tetras in a breeding net I have?

 

[The Betta boy]

Once I'm done redecorating I'll put them in the 55 gallon.

It could work, But if you see that the betta remains in aggression mode, you might have to cut them out of sight.

Alright. Thanks for being so helpful.
