quarantee tank 1 ft. Okay lah, not that small.
Not all wrasse aggressive though, though such as coris ,cleaner and carpenter wrasse are quite peaceful. It happen a while back, until when i release the wrasse in my main tank, then its start feeding, tested the quarantine tank water parameter, okay though.
Understand abt the dentrius part, probably juz an isolate case bah, the tangs doing fine. Now quarantine a goby inside, very hungry all the time.
Guess most pple will juz do partial water change to maintence their water condition for the quarantine tank. I added in a skimmer though, and , of course live rocks, 1 piece as I dun think i be using copper.
