Discovering new life in a reef tank is one of the most rewarding experiences for any aquarist. For years, observing Ricordea florida anemones, affectionately known as “Baby Rocks” by many in the hobby, has been a source of fascination. These vibrant anemones, popular for their color and texture, hold secrets to reproduction that are often learned through hands-on experience rather than scientific journals. This article delves into the captivating world of Ricordea florida reproduction, drawing from real-world observations to shed light on how these “baby rocks” come to life in our home aquariums.
One of the most exciting moments for a reef keeper is the unexpected appearance of baby Ricordea. In a thriving 120-gallon display tank, a surprising event unfolded – the emergence of approximately fifteen baby Ricordea anemones from a group of about twelve adults. This spontaneous reproduction highlighted the dynamic nature of reef ecosystems within our tanks and sparked a deeper curiosity into the reproductive habits of these fascinating creatures.
Driven by this initial success, a dedicated 16-gallon breeding tank was set up, housing over thirty Ricordea of various colors and sizes. Over eighteen months, despite witnessing around eight spawning events, the yield of baby anemones was surprisingly low. This experience underscores the unpredictable nature of Ricordea reproduction and suggests that a dedicated setup doesn’t guarantee increased offspring. It also led to valuable insights that challenge common misconceptions about their reproductive processes.
Contrary to some beliefs, Ricordea florida do not release eggs freely into the water. Instead, these anemones engage in internal fertilization. The female Ricordea takes in sperm, and fertilization of the eggs occurs within her body. Observations suggest a gestation period of approximately 25 to 30 days. After this period, the fully developed “baby rocks” are released from the mother anemone. This process is markedly different from many coral species that release both sperm and eggs into the water column for external fertilization.
While Ricordea florida anemones are colorful and contain zooxanthellae, enabling them to utilize photosynthesis, supplemental feeding plays a crucial role in their growth and reproductive success. Regular feeding, every week or two, with small pieces of silversides or shrimp, appears to significantly enhance their vitality and potentially increase the frequency of reproduction. Providing them with direct food ensures they receive adequate nutrition to thrive and produce more of these delightful “baby rocks.”
In conclusion, witnessing the birth of “baby rocks” in a reef tank is a testament to the intricate and often surprising processes of marine life. Ricordea florida anemones reproduce through internal fertilization, nurturing their young before releasing them as miniature versions of themselves. By understanding these nuances and providing appropriate care, including regular feeding, reef keepers can increase their chances of observing the fascinating phenomenon of “baby rock” anemone propagation in their own aquariums.
