my 2 cents:
why not juz approach one of the largest if not the largest ornamental fish/equipment supplier in Singapore; Qian Hu, for a similar grant to support ur school's research programme on marine biology. juz like what SIA has contributed to ur school recently for the Rooftop Garden in Dunman Sec Sch.
This way, all will stand to benefit. Qian Hu will stand to gain from its goodwill, Dunman will hv its influx of funds for research. Reefers all around will get to see the progress of ur school's research and will not lament on wasting taxpayers' monies.
3 birds with one stone and everyone's happy.
