New Research Reveals What Many Aquarists Already Knew

Some of the things that the scientific community is “discovering” are things that have been known for years by reef hobbyists.  I’ve been reading through some articles about recently published studies. A couple of them really got my attention as things that many hobbyist already know, just from keeping aquariums in their homes.

Distressing Damsels

Threespot DamselAsk a long time reef aquarist about keeping damselfish in a reef aquarium…they will probably tell you that damsels are aggressive, and sometimes destructive to a reef aquarium community.  A study recently published on PLoSONE.org found that Threespot Damselfish are damaging coral reefs in their efforts to find new habitat.  Read More »

Killer Algae – New Research on Creeping Caulerpas

C. taxifoliaIt is amazing how little we know about our ocean’s ecosystems! We know that corals can defend themselves against other corals, invertebrates, and to a certain extent fish, but a recent study has found that corals may have another attacker to defend against. Algae has always been a problem with coral and coral reefs as a whole. The rapid growth and expansion of some macro algae will eventually choke out specific corals, killing them in a matter of days. Taxifolia a species of Caulerpa, began invading parts of the West Coast years ago, choking out everything in it’s path as it spread. Normally, we think of the tangling tendrils of green smothering the corals in darkness as they take over, slowly starving them of vital light and nutrients. However, a recent study performed by a professor and his graduate student at Georgia Tech have found algae that can kill coral on contact.
