Small Aquarium One
The juvenile Maldivian anemonefish (Amphiprion nigripes) has grown in size and is better acclimatised to the aquarium, spending more time near the corals. The new zoanthid colony (Zoanthus mantoni) has been predated (by crabs or the seastar) resulting in a loss of polyps.
A new G. fasicularis coral mini-frame has been added, and we are experimenting with various transplantation methods (proximity, contact point, fragment size & orientation). Our Acropora coral mini-frame was showing some bleaching and tissue loss, so we removed the diseased fragments and relocated the frame to our coral holding tank for observation. 17 out of the remaining 21 fragments are now encrusting, and interestingly they show some interspecific growth variation (A. latistella is encrusting to the bar not the zip tie, whereas A. hyacinthus has grown over the zip tie but is not yet encrusted to the bar).
Small Aquarium Two
We have seen an increase in algal build up, particularly on the coral plates and rocks. This has also affected the mini coral frame, which was cleaned of algae (greater on the shaded side of the frame). Any paling corals were removed, and this frame was also relocated to our coral holding tank. 11 of the remaining 16 fragments are healthy. The Clark’s anemonefish laid 3 clutches of eggs this month, and we observed that (photo):
- Day 2-3: the eggs undertake significant organ development from the yolk sack.
- Day 7: on all 3 occasions, the eggs hatched overnight (with a few individual eggs hatching on Day 8).
