After several months with no known spawning attempts, the common clownfish pair (amphiprion ocellaris) in my display tank have gotten back into a regular breeding pattern. Since the beginning of September, they have spawned three times. Interestingly, they have designated a different corner of the aquarium as their breeding territory than the last time around. Their substrate of choice is actually the aquarium glass. In fact, I believe that my attempts to give them a ‘suitable’ alternate spawning substrate is what drove them out of their old territory, which is now occupied by leaning tiles and small panes of glass—all of which would allow me to easily remove the eggs to a hatching vessel on the day of hatching—but alas, the clownfish are disinterested in helping me in that cause and have just picked another corner of aquarium glass to spawn on.
I am also fortunate to have success getting a second pair of common clownfish (also amphiprion ocellaris)—originally hatched and raised by ORA—to initiate spawning twice over the past three weeks. This second breeding pair of clownfish I have had for less than a year, although the female was a mature-sized fish when I purchased them from a local fish store.
Unfortunately, about two months back, my phytoplankton culture crashed, so I need to get my phytoplankton and rotifer cultures back up and running if I hope to try raising any of the clownfish larvae.
Here are a couple of pictures of the second common clownfish pair (amphiprion ocellaris) , in and around the clay pot they use as a spawning substrate, guarding their eggs. These pictures were taken on the third day after spawning, and you can see the dark pigments of the clownfish larvae through the transparent egg casing. In just a few more days they will be ready to hatch.
