IceCap 4 Room Isolation Box

IceCap 4 Room In-Tank Acclimation & Isolation Box (IC-RF4D)

The IceCap 4 Room Isolation Box (SKU: IC-RF4D) is the largest option in the IceCap acclimation lineup, serving as an essential, high-utility husbandry tool distributed by CoralVue to dramatically lower livestock losses, curb territorial aggression, and streamline the introduction of sensitive new marine and freshwater specimens. Adding multiple new fish or delicate invertebrates directly to an established aquarium often triggers immediate territorial warfare from dominant tank residents. By utilizing the IC-RF4D, you can suspend new arrivals directly inside the parent display tank. This allows resident fish to see, smell, and visually interact with the newcomers over several days without any physical contact, safely neutralizing aggressive chasing behaviors before the new additions are permanently released.

What separates this professional acclimation system from traditional hanging containers is its highly unique, four-chamber modular layout and clever flat-pack footprint. The internal clear acrylic dividers allow you to house up to four specimens at once, making it ideal for introducing multiple schooling fish, separating breeding pairs, or nursing minor physical injuries in a protected space. The laser-cut slot matrix running along the side walls guarantees that fresh, filtered water from your primary aquarium continuously sweeps through the chambers, eliminating dead zones and maintaining optimal water chemistry. When your acclimation window closes, the entire box can be pulled apart in under 2 minutes, packing flat into a drawer to keep your equipment storage room clean and uncluttered.

Key Features

• Universal Hanging Adaptability: The sliding vertical tracking hook handles rimless glass profiles or heavy plastic molding tracks up to 1.75 inches wide without needing fragile suction cups.

• Breeder-Preferred Nursery Workspace: Excellent for isolating pregnant livebearers, protecting fragile fry clusters, or holding brooding mouthbrooders without altering your primary filtration loop.

• (Note: This system arrives as a set of flat, interlocking acrylic panels wrapped in a protective peel-away masking film. Minor toolless snap assembly is required prior to submersing the unit).
