Most fishponds near the shoreline are actually brackish. Baka ma-shock ang katomorpa kung bigla-in, mas OK kaya kung e-acclimatize dahan-dahan sa salt water?
Napaka hardy tong halaman na ito, kung marami pala dyan, ibuhus nyo na kaagad. Of course rinse it first in fresh water to reduce the risk of parasites and undesirable hitchhikers.
The Philippines is so rich in bio-diversity! Most of the time we don't know what we've got.
