Jamie's Dinoflagellate Journey
Why this thread matters? It is important to see how fellow reef keepers nurse their tanks through a dinoflagellate outbreak. It's not an easy journey and Jamie's latest update reports dinos have been gone for about two months.

Coral acclimatization to novel, co-varying stressors is associated with fitness trade-offs
Research on Siderastrea siderea and Porites corals shows acclimatization to combined stressors involves fitness trade-offs. Understanding how corals adapt physiologically to multiple pressures informs realistic husbandry expectations and species selection for challenging conditions.

The species - Hippocampus amandavincentae - was found by examining heaps of bycatch
Scientists identified a new seahorse species, *Hippocampus amandavincentae*, overlooked in bycatch for over a century. Seahorses are stocked in marine aquaria; new species descriptions matter for collection and identification.

Our friends at @noaa.gov are forecasting that the 2026/2027 #ElNiño could be among the strongest on record
NOAA forecasts 2026–27 El Niño may rank among the strongest on record. Severe El Niño events trigger coral bleaching, nutrient upwelling, and wild-stock stress; this is a critical outlook for reef systems.
