I kept this tetra in a community tank with larger fish, and it stayed active. However, it did attack a smaller fish, so I removed it after a week. Not recommended for mixed tanks.

The fish looks unique with its teeth, but it’s very aggressive. I had to keep it alone and it didn’t thrive. Not a good fit for most setups.

Only kept it in a tank with large cichlids. It stayed calm and active. The teeth are noticeable and it seems to feed on the scales of others. Needs careful pairing.
