I have a 55 gallon saltwater tank w/ live sand. We didn’t get live rock because I’m not interested in having a reef anytime soon. So I have let it run for about a month fish free. The other day my fiancee bought me 3 small yellow tail blue damsels. Well we brought them home and aclimated them for the legnth of time the lady told him and one of the fish acted strangely and the next morning was dead. We feed the remaining two live brine shrimp and the seemed to be happy and healthy in their new home. Well to my dismay another one is dead. We’ve checked the levels and everything seems fine except the pH it’s roughly 8.8 could this have caused my fish’s death? What should I do now?
Thanks
Your pH is a bit high, but your tank may not have completely cycled either. What levels are your Ammonia, Nitrite, and Nitrate? Also, even if you don’t put coral in your aquarium, you will still want a fair amount of live rock (1-2 lbs. per gallon is the general rule). Live rock not only helps with filtration (by providing a large surface area for nitrifying bacteria), but it also provides shelter for your fish. Just remember that Damsels can be very territorial, so you need monitor them closely with peaceful fish. In the mean time, you may want to do a large water change (at least 10%) to drop your pH.

Easy: Since your fish have been dying one-by-one the, it is hard to assume the PH caused it. If this was the case all the fish will be dead.
3 Damsels: Damsels are very very aggressive to their own kind. The answer to your question is simple. The dominant damsel killed the first one then killed the other one until he is the only one left.
Research on the compatability of any future fish you will purschase..
First Hand Experience.. Had 2 damsels the next day one was murdered. The “killer” is still alive after 3 years.

you can take a dead fish to your local aquarium and get(some one in tha know)to do an autopsy&they will be able to tell you exactly wyh the fish r dying.
