Ok the other day my
chevron tang died. Though maybe stress old age who knows. Today my new wrasse dead. Now my dotty back has many white spots over him. His time is coming to an end also
The only healthy looking fish in my tank are the gobies and
tomato clown. Corals are looking great the inverts like the anemone, shrimp, snails, hermits are also all doing great!
But 2 soon to be 3 fish in 3 days this SUCKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
My tank went from perfect to this in 3 days. The day before the chevron tang went he was normal then the day he died he wouldn't come out. Same with the wrasse yesterday normal today dead!
Tonight my dotty back looking like he should be dead i am sure by morning he will be
Tested my water and it is......
Temp-80
dKH-9.0
pH-8.2
Nitrates-5 (i am sure from dead fish in the tank)
i am going to be doing a 20-25 gallon WC on my 72gallon tank tomorrow. Got the water mixing since yesterday ready to go.
