How to Travel Cross Country w/ Saltwater Fish & Coral | Multi-Day Road Trip | Hilary On The Move
A guide documents transporting live corals and fish cross-country by car using sealed containers and power inverters. Practical logistics for one-time moves are useful but not broadly actionable for most hobbyists.

Global sea surface salinity and temperature impacts on trace elements, crystallography, and organics in massive Porites coral skeletons from a museum collection
Researchers show that sea-surface salinity influences trace-element incorporation in Porites skeletons alongside temperature. Clarifying skeleton geochemistry helps predict coral health responses to changing salinity and temperature regimes.

Rejuvenescence suggests recurrent coral responses in Miocene and modern reefs near upper thermal tolerance limits
Evidence of rejuvenescence—a coral recovery strategy after thermal stress—appears in both Miocene fossils and living corals, suggesting a persistent adaptive response. Understanding how corals have survived past thermal extremes informs expectations for modern bleaching events.

Beyond corals: unveiling the ecological roles of macroalgae in the Red Sea - a review
A review examines macroalgae as ecosystem engineers and food-web drivers on Red Sea reefs. Macroalgae dynamics directly affect reef structure and community composition in ways aquarists managing algae balance should understand.

A sharpnose snake eel slithered into Coral City… the first time we’ve seen this species on Camera in over 5…
A sharpnose snake eel appeared on a reef monitoring camera for the first time in over 5 years. Rare species sightings on established monitoring sites indicate shifts in reef-associated fauna composition worth tracking.
