Can Betta Fish Live With Scarlet Badis?
No, scarlet badis grow just 0.8 inches and are micro-predators. Bettas will eat them or stress them to death.
Why
- Scarlet badis grow only 0.8 inches and are carnivorous micro-predators that eat small invertebrates.
- Bettas will see scarlet badis as either prey or competitors and attack them.
- Scarlet badis are sensitive fish that need live or frozen foods and stable water conditions.
- They are territorial bottom-dwellers that will be harassed by bettas claiming the upper water column.
- The size difference is extreme. Even a small betta is many times the size of a scarlet badis.
What could go wrong
Bettas will either eat scarlet badis directly or harass them until the tiny fish dies from stress and starvation.

Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
Bettas do well with peaceful community fish of similar size like corydoras or otocinclus. Scarlet badis do best as a species-only setup in 10-20 gallons with tiny tankmates like cherry shrimp.
