If you are going to catch the Singapore angel for quarantine, i would also suggest to catch all the fishes out and leave the display tank fallow for at least 1 mth to run out the parasite cycle.
Also look properly at the spots... it may either be ick or velvet.
Oh yea.. i used to visit them when i used to stay at bedok areas. Sometimes i also do see the couple at pasir farmways too
Looking for small regal angel or juv blueface. Anyone??
Eastern update:
Irwana jus have a fish shipment, wrasse seen but i am no guru at that.
Pac marine have a fish shipment, lots of powder brown.
Regal angels
Emperor angels
lionfishes
flame angels and many more.
Ah beng n I aquarium is closed today.
Bro, PBT swimming against current is not good news, its a signal that ich may be giving it discomfort.
Would suggest u take it out for medication or apply hypo-salinity
