Obet, okey lang mag uwi ng isda as for corals medyo may konting risk.
Remember not to declare this on the airport where you will be departing, in your case Macau airport. Hahanapan ka sa Macau Airport ng quarantine certificate.
As for sa Phils. Customs, dineclare ko yung dala kong 7pcs na isda and 3pcs. corals. Naka box yung mga isda and corals and check-in luggage din. Pinabuksan yung box, check ng customs and ng BFAR mga isda, no comment, yung coral tinanong sabi ko mga bato lang, bahay-bahayan ng isda. Swerte yung palys ang nasilip na corals kaya mag live rock. After inspection, okey na no fees, lagay or anything.
Sabi customs, buti declare ako daw kasi minsan pag nagsinungaling at nakita nila dun nila pinahihirapan. Basta, daw konti lang they let it pass. Thats was my experience but I can't guarantee it will be like that always. HTH.
Since, this will be your first time, suggest mga isda na lang muna.
