Our Marine Aquaria
In Aquarium 1, our two Pistol shrimps (Alpheidae sp.) excavated the sand from beneath the rocks, causing instability in the structure. So, we returned the shrimps to the ocean, and we are currently undergoing a redesign:
- a small colony of Galaxea fascicularis fluoresces neon green and makes a nice addition;
- a new dome-shaped Mushroom coral (Fungia) has extended tentacles to feed throughout the day;
- a starfish (Linckia laevigata) with a very small body and one long arm is showing noticeable signs of regeneration.
- the mini-frame coral fragments (transplanted two months ago) are showing signs of encrusting and fusing.
Aquarium 2 suffered from excess air entering via the inflow. With many tiny bubbles accumulating under rocks and in the water column, one Domino Humbug suffered from bubble eye syndrome (so we immediately released it, for a natural recovery back in the wild).
Recent additions to this tank have been collected near the reef crest:
- Brain coral (Platygyra);
- small Giant clam (Tridacna gigas) showing off its blue-purple coloured tissue;
- small colony of Sun coral (Tubastrea coccinea) – an azooxanthellate, and thus needs to capture its own food (we have so far not seen the tentacles extended, so we will try other foods).
A leftover fragmented colony of Acropora digitifera with large areas of exposed skeleton will be monitored, to see how it heals and recolonises over time. The larger Clark’s Anemonefish (Amphiprion clarkii) has claimed the anemone, and will actively chase off the smaller one if it gets too close. The smaller Clark’s has claimed the mushroom coral, and is frequently seen swimming around and retreating to it.
