• Water pH 6.0–7.5 · soft to moderately hard water for confirmed Eigenmannia. Keep ammonia and nitrite at 0 ppm.

Tankmates and setup*

Shy and social with its own kind. Provide shaded hiding places and avoid fast feeders or fish small enough to be eaten.

* Temperament varies by fish and setup.

Feeding

Offer thawed small invertebrates after lights dim. Watch each fish eat before relying on prepared food.

Try an appropriately sized portion of Hikari Bio-Pure Frozen Blood Worms if accepted, as part of a varied diet.
