    Hi guys,
    I bought a bicolour angel last week, from a reputable LFS, it unfortunately didn't make its first night, dont know why, my tanks been running for 3 years, lots of swimming and hiding spots, parameters in check, i dripped the fish slowly for about 3 hours in low\dark light, (sump), after lights out in DT, I transferred it to the DT, and then found it dead the next morning, okay but since then, iv had 2 other long established fish, die also. could it be related, the other 2 fish didnt look sick, could the angel have brought in something, Oh i also bought a Bubble coral the same day, all my coral is doing great, please any recommendation to prevent more death, help pls

    if it happens at night and your fish shows no signs of being sick its possible that you may have a crab or something hiding that comes out at night that attacks sleeping fish. The fish you bought might have been a bit weak,stressed and that something couldve attacked the fish. Did the bubble coral come on a piece of live rock? as Alan said,please give us your water parameters.

    over what period did the 3 fish die? (proximity to one another as in timeline) and what are your readings specifically alk and ph..

    ph swings can cause low oxygen levels and bigger fish will succumb to these low oxygen levels quickly..

    so it is important to test Ph early in the morning for a true reading as it dips at night..

    but more info on the system may help us in picking up something that you may not even be considering to be a probl.

    Dripping fish for 3 hours could be the problem. I have never dripped a fish for longer that 45mins and have never lost a fish due to acclimatisation.

    i agree dripping for 3 hours is only advisable if it came from very varying salinities from your main tank

    Bicolor angels are very difficult even though they are often available, very few thrive in captivity, many are improperly collected as well. Always make sure it is eating before you buy it and beware of this species as they require expert care in many cases.

    The longest i have kept a Bicolor was 6 years and this is not good when you consider other centropyge can live for 20 years plus.

    The vast majority dont live past 1 year, they are the moorish idol of centropyge in my opinion.

    The fact that 2 other fish have died means something is likely brought in by the bicolor or the coral that your introduced maybe oodinium? did you see any symptoms of disease? Fast breathing(rapid gill movements) usually the first sign something is wrong?

    Salinity is a bit low, although not critical, but do try and get it up to the normal range of 1.024 to 1.026.

    Your temperature fluctuation is a big concern, why does the temp drop to 23, do you not have a heater in the tank?

    I have never heard of aiptasia killing a fish, unless it ingests it accidentally.

    My advice would be QT everything wet including corals going forward.
    Bi colors are tough to acclimate to aquarium life
    What are your Ammonia and Nitrite levels?

    yes the temp thing, 1 day its sunny outside and temp ranges from 24 to 27.5 got MH obviously contributes a lot, so i put heaters off, then the next day its cloudy and cold and it drops to 23, must i just leave the heater/ or heaters on and on what temp?

    I would just leave the heaters on. They will switch off when they reach the maximum temp you have set it on.ex They wont heat the water to 30 degrees if you set it on 25.it will switch off when on 25. You gain nothing by switching off your heaters. By leaving them on you will not have the big drop in temp.
