Fishes dying dont know why help pls

my long nose butterfly died and right after the next morning a black back butterfly died i have no idea why the long lose butterfly had a red mark on its mouth and hair bubbles all over on its fins and body which were really odd i been on top of the water tests everyday nitrite and ammonia never reached close to .5 ......could it be there is a sickness in the tank

 

your ammonia and nitrite should be zero. and nitrate should be less then 20.

fill out this as much as possible

 

How large is your tank? Butterflys usually need quite a bit of room to swim and if you don't have the right home, they will get stressed and die.

 

its 60g

 

Bummed out over your losses but we will need to know some things and most everyone on here will be helpful.
1.)Pictures are vital to diagnosing problems?
2.)How long has the tank been running?
3.)Water are your exact water chemistry numbers?
4.)What size tank and equipment you have?
5.)What livestock you have?

 

#5 could be your issue in a 60 gal - You would be surprised when fish get to maturity and how they start to take over territory.

 

Temperature: 80
PH: 8.3
Ammonia: less then 0.25
Nitrite: less then 0.25
Nitrate:less then 5.0
Salinity: 1.22

Test kits you own: yes
Liquid or Strips: liquid
Brand Name: API Saltwater Masters tests kit
Are they Expired?: no


Tank size? 60

Reef, fish only or, freshwater? Reef


How long has your tank been set-up? 3 months



Live rock? yes
How much? 80lbs
Did you recently add some? no

Filtration. yes
Type? sump
Protein skimmer? yes

 

Ammonia and Nitrite should be 0. I would also suggest getting better Test Kits if possible...i.e. Salifert. I owned 2 API kits, and both were very inaccurate on some tests.

 

I would work on getting ammonia to zero before assuming a disease unless you see any obvious symptoms.

 

i could have sworn butterflies needed like 100+...probably wrong.
