Aside from money, syempre, limited supplies nila.. mahal tlga kasi mag-iimport pa sila from other places (e.g. Philippines) so pagdating ng araw na maubos coral reefs natin (di kasi masyado strict pagdating sa ganito dito sa tin), tataas din prices kaya kelangan mag-frags kung pede na syempre, not only to save money, but also to help protect our coral reefs.
anyway, i heard na pede fluorescent lighting kung low to moderate lighting lang kelangan ng corals mo. kaya ung di demanding sa light mga corals ko, except dun sa nabili out of impulse (w/o researching first..hehe) BEFORE some people(namely sirs apol, fugu, chonglai and jolt! etc..) taught me the basic do's and dont's of reefkeeping...
