1. Soft Coral Growth Sasha and Liza

2. In our proposal we asked ourselves a series of question… 1.Which coral will grow the fastest? 2.How long does it take it coral to reach its maximum size? 3.Will the corals grow faster or slower in the wild? 4.Can we feed the corals certain nutrients to make them grow faster? 5.How will the corals interact if one gets too big?

3. Hypothesis: Under the same conditions the mushroom coral will grow more than a branching, soft, coral over the course of the year.

4. Original research plan: ●Grow four different soft corals… calculate which grows the fastest ●Count how many times the stalk split (Sinularia) ●Count how many times the polyps divide (Rhodactis) ●Count the bunches of polyps

5. Our Corals

6. Rhodactis Originally from tank A. Fragged by cutting a small polyp off the original coral and placed it into the tank

7. Nephthea Originally in tank 8, we did not touch this coral AT ALL. It stayed in place the whole time unlike the other corals that we have to move around a couple of times

8. Silver Xenia Ordered online. Originally put in the Frag tank. Eventually we moved it into tank 8 because it thrived in the Frag tank

9. Neon Green Sinularia Ordered online. Started off on the bottom of the tank and then had to move it multiple times to get the correct air flow

10. Material and Methods: ●Measurement grid ●Tank ●Corals ●Lifeguard ●Refractometer ●pH testing kit

11. Data Collection Sheets:

12. Each square is 1 cm by 1 cm Measurements

13. How to propagate (frag) soft coral... 1.Obtain desired coral 2.Place coral in shallow water 3.Prepare the plug and glue 4.Pick up the coral and snip a small part of the stalk off 5.Put glue on the plug 6.Place the stalk of the coral on the glue 7.Once dry place in the tank

14. Tank 8

15. Data Collected

16. Data: Monthly Averages

17. Graphs:

18. Average Length

19. Average Height

20. Which coral will grow the fastest? ●Hard to determine ●Different starting points ●Soft coral absorb and let go of water so they can grow and then shrink

21. How long does it take for each coral to reach its maximum size? ●Unknown ●Average size can range from.25in to 4 ft. ●Grow up to 4.5 cm per year

22. Will the coral growth in tank 8 be faster or slower than the average time it takes for a coral to grow in the wild? ●Grow better in a controlled environment

23. Can we feed the coral nutrients to help them grow faster? ●Other than being fed every day, the corals were not targeted to grow faster

24. How the different corals will interact together, if the corals get too big? ●Question wasn’t fully run because the corals were never too close together ●Sinu and Mushroom coral did occasionally touch but nothing happened

25. Discussion Over the course of the year the mushroom coral did split the most and seemed to remain a very consistent healthy size relative to the other three corals.

26. Conclusion:

27. Challenges ●Corals shriveled ●Had to move corals many times for better water flow ●Had to change tanks from the Frag to tank 8 ●Even with water flow we couldn’t find out why some of our corals shriveled

28. Future Directions ●Grow corals near power heads, so the corals get a “natural” amount of water flow ●Do not have other specimen in the tank if you know that a certain species eats any kind of coral

In this article, we learned how to frag soft corals and mushrooms. This site gave us the idea to cut the mushroom corals off with the rock still attached so we can then frag the corals. Since mushroom corals have slimy texture, it is very hard to attach them to plugs for fragging, but if it is attached to a rock, the rock texture is easier to glue onto the plug. Saad, Sudirman.
