Hi, I've been a frequent visitor of this site for a couple years now, but recently I've been stumped.
Background info
7 month old tank, 400L (330DT + 70sump), 50kg LR, 12k LPH combined flow, mixed reef. skimmer, pearl reactor.
2 common clown, 2 4 stripe damsels, 1 blue Fiji damsel, 1 hippo tang, 1 yellow tang, 1 bi-colour angel, 1 six line wrasse, 3 blue cheek chalk gobies, 2 skunk cleaner shrimp, 4 red leg hermits, 8 astrea snails, 2 cerith snails. (1 flame angel)
I feed New Era marine pellets, red & green marine enriched seaweed strips and frozen Mysis, brine, red plankton and lobster eggs. minimal feeds, alternating daily, once a day.
Test results, NH3 = 0.00, NO2 = 0.00, NO3 = 1.00, PO4 = 0.05 Kh = 10.5 Cal = 460 Mag = 1360 pH = 8.1
Firstly I bought a coral beauty, then within a couple days it was hiding in my rock, I didn't see it for a whole day, the next morning I went hunting for and found it on its side under a rock, still alive, I destroyed my rock work & fished it out by hand, took it back to LFS for an exchange, the bi colour angel. which is still alive, the flame angel I bought the day after the coral beauty, is now dead, I saw it resting facing up on my rock, and after watching it not move for 10 mins, fished it out, by hand and put it in a breeder net. it was still alive, then within 1 minute it was dead.
All of my other fish are still active and feeding and swimming around, there is no aggression in my tank. I have some soft, some LPS and some SPS. everything is thriving.
now, I know my LFS had a dying BTA in their system, a big one, for sale, could that have contributed to these deaths or is there something that only affects dwarf angels that I have overlooked? I saw a brown spot sailfin tang in the same tank as the BTA that looked exactly what these fish have done, lying on the bottom, gasping for air etc.
luckily the fish is still in the 7 day guarantee, so I haven't lost £70 ($110).
any ideas?
