Ha Ha
Long time since I last went to Sentosa. Not really my cup of tea
there.
Qian Hu, only have 5 rays there in total
2 Henleis ($1000/pce) but they removed the spine 
2 Motoros ($160/pce)
1 Rec ($80/pce) the Rec was only 4" but very beautiful male
ray
Also went to Hougang there the aquarium but they only have 1 Sakura
ray there. Think must wait till ray season in June
