Exciting research has revealed new insights into coral bleaching. By studying the pest anemone Aiptasia pallida, scientists found how Cnidarians induce their own bleaching after exposure to high temperatures!
The intensive use of powerful lighting above marine aquaria is common practice amongst aquarists nowadays. This is now regarded as a necessity for keeping healthy and fast growing corals. Recent studies have indicated that this philosophy is just part of the story…
Coral reefs; what exactly are they? Read this article and step into the wonderful world of tropical coral reefs, supported by beautiful images from photographer Hans Leijnse!
The use of supplements in the (marine) aquarium has always been controversial, dividing hobbyists into two camps. The question is; do supplements really matter? Let's take a look at amino acids; a popular additive nowadays.
Global warming is seen as the number one threat to the world's coral reefs, next to overfishing, pollution and eutrophication. It is common knowledge that elevated sea surface temperatures may cause coral bleaching. That an increase in atmospheric CO2 could be just as threatening, is not.
