Coral Cat Fish

About this fish

Coral Cat Fish is the shop name for Plotosus lineatus, an unusual reef-associated catfish kept in the home saltwater aquarium. This fish is typically chosen for its distinctive look and behavior, and for aquarists who want a larger, predatory-style marine fish. In the aquarium, it is most practical in a mature, stable setup where feeding can be managed and any small “prey” animals are avoided. As with many uncommon marine species, researching adult size, diet, and compatible tankmates before purchase helps ensure a good long-term match.

Features:

• Venomous fin spines: use care when netting or handling
• Often schools when young, becoming more individual as it grows
• Predatory feeding style—benefits from meaty, varied foods
• Best kept in a mature, stable system to support recovery after acclimation
• Needs appropriate tank space as it grows to a large adult size
• Works best with tankmates chosen to avoid being seen as food
