Peaceful mid-dwelling nano fish like ember tetras, harlequin rasboras, and celestial pearl danios, but keep them in strong groups

Bottom dwellers like Kuhli loaches, Corydoras, Malaysian Trumpet snails.  Depending on each individual betta, dwarf shrimp may or may not get eaten. Avoid other aggressive, fin-nipping or even colorful fish like tiger barbs and fancy guppies. Prevent stressing the betta by keeping top dwelling fish to a minimum. Avoid larger fish which can prey or intimidate like cichlids.

Notes

Betta fish are also known as Siamese or Japanese Fighting Fish.  They're very territorial and should never be kept together unless for short-term breeding.  Despite their aggressive nature, they can have a curious and playful personality.  They'll often recognize their caretaker and will even come up to the glass to greet them.  The betta spenden species come in a variety of tail shapes, colors and patterns.  They're easily the show piece to any tank and their extravagant tails flow like living art.  Provide their space with a lot of plants, slow water agitation and warm waters to keep them healthy and active.

Regardless of what you see in retail stores or what people say, NEVER keep a betta in anything less than a 5 gallon tank. https://plantedtankmates.com/types-of-betta-fish/
