    I got a sailfin tang about 2 months ago. He was doing great, eating well, even eating out of my hands.. He's stopped eating about 2 days ago. Water parameters seem fine, all other livestock happy.

    PH: 8.0-8.1
    ALK: 9.3 dKH
    PO4: <0.25
    Nitrite:0
    Ammonia:0
    Nitrate: Don't know, last tested <10ppm

    He's not very active, seems slugish..

    Any ideas?? Please help before its too late..

    Have you added anything to the tank in the last week, like new fish or corals

    Your paramaters looks fine. Fish mostly get affected by Ph and salinity, so check salinity. Did you add the phosguard in a reactor or in a mesh bag. Did you check if the quantity you added is rated for the tank capacity

    Salinity at 1.024. I added the phosguard in a mesh bag, my P04 was quite high 5 days ago, problem with RO unit. It dropped significantly since i added phosguard. Seems like adding the phosguard also dropped my alkalinity and probably my PH. Is this possible? The package rates the phosguard treats 300-400L, my tank is within this range..

    hmm wierd i would suspect black ich but it is usually smaller spots for that but it matches the behaviour you are seeing, but they only on one side so it may not be this.

    i would try catch it and treat in Quarantine or hospital tank /container of sufficient size if this is possible but before you treat you need to observe it well and try determine what it is that is ailing the fish.

    Hey Colbar, the mysterious illness spread to my regal tang. Thats the feedback i got from my wife, im in london for a week so she's looking after the tank. Last night when i heard the regal tang was also not eating, i had the wife remove the phosguard, and today evening both tangs are eating :confused1:
