Species Profiles
Serpae Tetra
Hyphessobrycon eques
Serpae tetras are vibrant blood-red schooling fish with a distinctive black comma-shaped marking behind the gill plate. While beautiful, they have a reputation as fin nippers — especially in small groups. Keeping them in schools of 8+ in a spacious tank significantly reduces this behavior. They add bold color to community tanks when kept properly.

The electric blue Jack Dempsey variant is significantly less aggressive and more colorful.
