If you read the paper by Zac Forsman from the Hawaii Institute of Marine Biology published in 2011 on the results of different commercially available artificial coral food feedings being tested you'd keep using the chilli and reef roids
' The average overall (pooled across species) weight increase for
the control (filtered seawater) was 2.1%, which was lower than
all other treatments. The tanks fed with Oyster Eggs, and
Roti-Feast had slightly higher overall mean weight increase
(2.7% and 3.1% respectively), but these differences were not
significant according to post-hoc tests. Reef Chili and
Reef-Roids on the other hand show a comparatively large
overall weight increase (6.5% and 7.5% respectively). When
the contribution of each species was examined, it became clear that M. capitata showed the highest increase in weight,
followed by P. damicornis, with Reef Chili and Reef-Roids
showing the largest increases (Figure 4). '
The bottled garbage many use were also tested.......
' Adding food supplements (MicroVert, MarineSnow
Plankton Diet, Phytoplan, and Salifert) at the manufacturers'
recommended dosages, resulted in no significant difference to
the controls (ANOVA, P ¼ 0.604). Unlike the feeding experiments
in filtered seawater above, these comparisons among
the types of coral food (pooled over dose) indicated no significant
differences with controls (ANOVA: M. capitata P ¼ 0.30,
P. compressa P ¼ 0.368). Adding either 3 or 10 times the recommended
dose generally resulted in a decrease in growth
(Figure 5). There was a significant trend towards decreased
growth with increasing dosage (pooled over food types) for
M. capitata (r2 ¼ 0.95, P , 0.024). Although the trends for
P. compressa (r2 ¼ 0.59, ns) and for both species pooled
together (r2 ¼ 0.80, ns) were not significant (Figure 6), the
trends were in the same direction and had a similar slope.
Phytoplan and Salifert treatments consistently had the
lowest growth rates for both species although these differences
were not significant. '
