About this fish
About this fish
Panther Grouper is a predatory reef fish sold under the scientific name Cromileptes altivelis. In the home saltwater aquarium, this species is best used as a centerpiece predator in a fish-only setup, where its feeding instincts and size can be managed safely. Because groupers are well-known for swallowing smaller animals, this fish is most practical in tanks designed around secure rockwork and appropriately sized, robust tankmates.
Features:
- Predatory temperament: will eat any fish or crustacean small enough to swallow
- Better suited to a large fish-only aquarium, not a reef full of small invertebrates
- Needs plenty of rock and secure hiding spots to feel settled
- Feed a variety of meaty foods such as frozen silversides, squid, and shrimp
- Best fed a few times per week with an emphasis on meaty, protein-rich choices
- Arrives as a sizeable predator; acclimate slowly and allow quiet time to settle in
- Choose tankmates that are large and robust enough for long-term compatibility
