Hmm, is the Betta in the 29 gallon? If she is, then this may not be the best choice, but croaking gouramis and pearl gouramis (there's many more smaller gouramis as well) are great choices, they need groups but have big personalites and don't look like Bettas (but are related, Bettas are technically a type of gourami). I would research more though, I don't know how well they live with endlers, but they probably would do just fine, as long as the Betta has her own tank and you don't overstock.

If you wanted another huge tank with a huge fish, a giant gourami (althought ugly to some) is a great choice solo, but many people don't have the money for a huge tank.

 

What about thread fin rainbow fish? You would need six of them. 3 male, 3 female.
the males display for the females and look very pretty. They stay about middle of the tank so shouldn’t pick at your cories or bother you betta?
let me know what you think after you look at them 🤘🏻

 

I would love to have a croaking gourami but I don’t think it would go well with a betta. What I have in mind are peaceful, non schooling fish that have individual personalities and characteristics.
Would a single honey gourami work? I’ve heard they are generally peaceful and my betta doesn’t attack anything unless it’s food (not even cherry shrimp).

 

I believe honey gouramis usually only do well with King Bettas, the big boys. If this is helpful, rocket shaped tetras don't nip as much as ones more like black skirts. Your Betta sounds very peaceful, so it might be worth a shot to try the honey gourami, but make sure to have a back up plan.

 

My betta has pretty short fins. Even though she is peaceful, she can still stand her ground and flare at a fish that gets too close. I think a honey gourami would if it leaves her alone.

 

Hmm, I welcome you to give it a go! I would just watch carefully, and prepare a back up plan.

 

It is not advised to house a betta with any other anabantoid (gouramis, paradise fish etc).

 

Female bettas are still bettas, and all bettas Have Opinions on what is in the tank with them.

Rebecca is 'peaceful' with what you have now - a bunch of fish who don't bother her and/or occupy parts of the tank she doesn't and most likely get out of her way when she gives them The Look (you know which one!). She's Queen of Your Tank.

You put a 'big personality' (usually means aggressive) fish in...she will feel the need to make him or her Bow to The Queen. If newbie doesn't react well because they've got a 'big personality' you've got two fish that are going to beat the crap out of eachother until one yields or dies. And they're going to do it often.

There are many small fish that are just as interesting as 'big personality' fish, such as the various rasboras which have different species behaviors (for instance in my tank the kubotai was independent and had a weird mutual relationship with my male betta, while the blues are shy and tight knit, but have a member who stays away to surviel predators and sound alarms), and will add more color and personality without big potential for fin-ripping fights.

My betta is not aggressive. I have an example that proves this. The endlers sometimes nip the dead skin off her body (never her fins) and she doesn’t even flare at them. She could kill any one fish in the tank but she doesn’t.
Also, do any of anyone else’s fish do this?
