I have a 55 gl FOWLR tank that has been up and runnng for 3 years.
I had a Clown, Chromis and Blue Fin and Yellow Tail Damsel.
My Blue Fin was quite the bully so until he passed on I didn't add any new fish. Inherited him with the love rock we bought when setting up the tank.
Spike finally passed a few weeks ago and I went to the local SW fish store and purchased 2 female Basselet Anthias.
Water parameters were perfect, drip acclimated them. Put them into the tank. All 3 were dead by morning.
Went back to fish store who were kind enough to give me a credit and purchased a Yellow Tank and Strawberry Dottieback.
I also purchased 3 more Anthias Male Lyretails from another source. This was yesterday, Drip acclimated them, tank water parameters fine. Woke up this AM, again all three Anthias were dead as well as the Dottyback.
Through all this both the Clown and Chromis are fine. As well as the 3 Turbo Snails.
Yellow Tank is doing well too.
So I am at a loss as to what is happening to my new fish. Except for the Tang all have died within 24 hours.
Any ideas as to what the cause may be? This tank has been fine for over 3 years.
