Help is needed big time here, I donít know where I am going wrong and its stressing me out way too much.
First of all here is the list
white T8 /BLue T8
Eheim Bucket filter (Large) - (filled with substrate and sponges)
steriliser with powerflo
Powerflo sitting at top X2
Dead coral rock from one end to the other
Live Rock (8KG)
Water hardness is perfect
2 heaters (heat is at 82-84F)
Twice every two days. Morning and evening
All around 3 weeks ago.
I had the following fish and stress had.
Dog Nose Puffer
Damsel (Black with one white spot)
Clown sweet lips X2
Green bird Wrasse
Black and White Damsel
Many hermit crabs and snails
All these fish were happy swimming, eating when fed all established fish. One day I woke to find that the Black Damsel was breathing heavily.. checked the water quality and it read that levels were the same as above, regardless did a water change at 15%.
Breathing went back to normal and the Damsel was swimming happily for four days, Trigger was a very bluey/black colour which on the fourth day I noticed its colour was not right I was pale.
Fifth day: all these fish were wiped out dead.
All crabs and snails are fine. The only survivor in the fish region was a small Valentini Pufferfish, with no marks, defects health issues nothing!!!!!!!!!!!!!!!
I took my self to the aquarium and asked what went wrong and they couldnít explain. Also took a water sample nothing came up from the aquarium at the shop.
I left it for a few days did a partial water change (30%) and left that for a few days.
Paralyased by the death of these fish who have been around for good while now) 8 months longest survivor is was 1.3 years old... I was keen to refill the tank back up with some fish but did not want to get a bite of money dropping if they die. So I bought 6 emperor damsels. My wife didnít tell me but she decided to buy more fish and place them in the tank (I have taught her how to put fish into the tank (slowly and leaving them to float for a little bit add water and leaving to float again before taking them into the tank).
So now I had 3 tiny emperor damsel, 2 clown fish, regal tang, valentine puffer and a blue damsel, oh Also she bought a queen trigger.
Woke again this morning to find that the following are missing
Regal Tang Missing
Both clowns Missing
6 fish missing over night, no trace. The larges was the regal tang at 1.5 inches
So I only have the following fish/life in the tank now who are again active eating no underlying problems that I can see.
Various hermits and snails
And a normal crab (patterned)
Also I have two anemone
All these fish are alive and well, the water is crystal clear the quality, temp, is perfect or so I think unless I am missing something obvious I also mixed a crushed garlic clove in with the food this morning to boost their immune system.
PLEASE HELP INFORM OF WHAT I CAN DO TO SORT THIS MESS OUT!!!
I have a feeling more deaths will occur and that I am blind to is happening and neither I or my local has a clue.
I would appreciate any help as this is too much and I do not want to add more fish, wife has been informed not to buy anymore until I know what is going on.. also this is costly way!!!
One other thing that filter was cleaned in saltwater
from the tank.
I have had aquariums for almost 7 years now
