| We have a freshwater fish tank community of tetras, catfish, gouramis and loaches. |
| Like many tetras, the glowlight tetra is a schooling fish and prefers to swim in the company of at least seven of its peers. |
| The freshwater mollies and tetras are rather ferocious and may take chunks out of your skin like miniature piranhas. |
| He's lived happily for the past four months with a platy and two neon tetras in a five gallon aquarium. |
| Rosy and rummy-nosed tetras and uaru cichlids swam en masse. |
| Pachon Cave in northeastern Mexico supports a population of blind Mexican tetras isolated from base-level populations by elevation. |
