Clownfish Larvae Death

Albert B Ulrich III Uncategorized Leave a Comment

Just wanted to complete the most recent clownfish spawning blog and post the (dismal) results.  Over the first two days post-hatch (almost sounds Shakespearean…oh, no, wait, the phrase I’m thinking of is ‘post-haste’, but even if not Shakespearean, the story does end in tragedy) the handful of clownfish larvae that …

Here are the photos of the clownfish eggs from tonight, prior to hatch.   Larvae look highly developed through the egg casing. Amazing how strongly the eggs are attached to the glass.  Both the male and female reacted to my presence today and were thrashing about next to the nest.  The …

Day 5: Now, approximately 5% (or less) of the clownfish eggs have developed eyes.  As the clownfish eggs sway in the current gently, the eyes are visible in a few.  It does appear that the spawn has been thinned out a bit by the male.  Hatching should commence in about three …

Yesterday, a pair of Amphiprion ocellaris (common clownfish) spawned in my display tank.  This is the second time the clownfish have spawned in the last two weeks—the size of the spawn is larger than the first time.  In addition to the typical flake ration I feed the display tank, I added …

Dosing Phytoplankton

Albert B Ulrich III Phytoplankton Culture Leave a Comment

Phytoplankton are small photosynthetic organisms considered to be one of the building blocks at the base of the coral reef food chain.  Many filter-feeding invertebrates depend on phytoplankton as a significant source of nourishment.  Within the saltwater reef tank, however, phytoplankton are generally not present in abundant numbers.  As a result, advanced aquarists often …
