The Chaetodon Kleini - Kleins Butterfly (Medium) is a high-utility architectural species, engineered for precision biological control in marine systems. Characterized by a burnished golden-tan body with subtle vertical banding and a high-set dorsal profile, this Medium variant is a masterclass in functional aesthetics. In the "Answering Machine" era of technical reef husbandry, the Klein’s Butterfly is highly prized for its reputation as an efficient predator of nuisance Aiptasia anemones and its overall hardiness compared to more delicate butterflyfish species.
Unlike more specialized corallivores, the Klein’s is a facultative feeder with a robust metabolism. It serves as a tactical addition to larger systems where control of pest anemones is required without the fragility associated with other species.
Note: Images shown are stock images and not the actual fish you will receive.
Care Level: Easy to Moderate
Temperament: Peaceful
Variant Size: Medium
Minimum Tank Size: 55 Gallons
Diet: Omnivore (Known Aiptasia consumer)
Reef Compatible: With Caution (May nip at soft corals/polyps)
Max Size: 6 Inches
Temperature: $72^\circ$ to $78^\circ$F
dKH: 8 to 12
pH: 8.1 to 8.4
Specific Gravity: 1.020 to 1.025
The Klein’s Butterfly requires a stable marine environment with significant structural complexity:
Structural Layout: Provide ample live rock with numerous caves and overhangs to simulate its natural reef-slope habitat.
Swimming Lanes: Maintain open horizontal space; this species is an active forager that requires constant movement.
Acclimation: Ensure the system is mature with established biological filtration.
These are generally peaceful residents that integrate well with other medium-sized marine fish such as Tangs, Angels, and Wrasses. While often used for pest control, they are "reef-safe with caution" as they may transition to nipping at certain soft corals, zoanthids, or leather corals if underfed. Avoid housing with hyper-aggressive species that may outcompete them for food during the initial introduction phase.
Success with the Medium Klein’s Butterfly hinges on a diverse nutritional protocol. While they are often brought in for Aiptasia control, they should not rely on them as a sole food source. Provide a varied diet of high-quality mysis shrimp, vitamin-enriched brine shrimp, spirulina, and specialized marine preparations at least twice daily. Maintaining stable salinity and high dissolved oxygen levels is mandatory for long-term health and vibrant coloration.
We’ve dialed in the logistics for national Overnight Delivery to ensure your livestock arrives in peak condition. Every order is packed using professional-grade insulation and climate-contingent heat or ice packs, designed to maintain stable temperatures throughout the journey. We handle the technical side of the move so you can focus on the acclimation. Our protocol is built on getting these fish from the facility to your tank with zero compromise on health or vitality.
