Captive-raised Tridacna Clams are relatively easy to care for in aquarium conditions. All clams in this genus harbor symbiotic algae called zooxanthellae. These algae provide most of the food and nutrients the clams need to live. It is important to provide the necessary amount of light to keep their symbiotic algae flourishing. Some species, such as T. Maxima and T. Corcea, prefer to be on rock surfaces high in the tanks under higher par. In contrast, T. Squamosa and T. Derasa are “sand” clams and prefer to be on a sand bed under lower Par. Some aquarists supplement feed with commercial phytoplankton cultures. Tridacna clams do filter feed on this type of plankton, but do not depend on it.
The Cortez Angelfish is a unique and eye-catching species native to the Eastern Pacific. While wild-caught specimens can be challenging to acclimate, these captive-bred juveniles are far better suited for life in home aquariums, offering improved hardiness and long-term success.
As juveniles, Cortez Angelfish display brilliant yellow and electric blue striations running along the body, making them exceptionally striking at smaller sizes. As they mature, this vibrant juvenile pattern gradually transitions into a more subdued green-blue adult coloration, highlighted by a bold yellow stripe extending over the gill plate.
This species is not reef safe. Cortez Angelfish are known to pick at corals and clam mantles and are best kept in fish-only or FOWLR systems where their natural behaviors won’t pose a risk to ornamental invertebrates.
Best kept in:
Fish-only or FOWLR aquariums
Mature systems with stable water parameters
Tanks with ample swimming space and rockwork
The Cortez Angelfish is an excellent choice for aquarists seeking a distinctive, captive-bred Pomacanthus species with striking juvenile coloration and long-term aquarium adaptability.
ORA’s captive bred Mandarin Dragonets do NOT require live foods. Ours readily feed on pellet and frozen foods, making them an easier to keep and ethical alternative to difficult wild caught Mandarins!
Synchiropus splendidus – Mandarin Dragonets are inarguably one of the most beautiful species on earth, which makes them very popular aquarium fish. Our mandarins have a mix of blue-green and red coloration on the body and deep blue accents on the fins. The coloration may appear different in varying lighting spectrums. These photos show what our mandarins typically look like.
Unfortunately, the natural diet of wild caught mandarins is live food, which can be tedious and costly for many new hobbyists to provide, especially in immature or small tanks. Even if provided the best captive conditions, wild caught mandarins often succumb to wounds inflicted by spear guns or toxic cyanide used during the wild collection process. An overwhelming number of wild caught Mandarin Dragonets die in captivity for these reasons.
