PLEASE don't feed the fish.
Some of the reasons to avoid feeding the fish:
1) not their natural food source (bread contains yeast and is bad for fish digestive systems)
2) changes behaviors - more fish of certain species show up to eat in large groups (typically yellow tail snappers) and can lead to more aggressive fish on the reef (when they don't get food and expect it)
3) changes reef environment - fish learn to rely on handouts and eat less of the algae/detritus on the reefs. Excessive buildup of algae contributes to coral growth decreases and mortality.

Thanks for helping us and our BVI reef systems out!
