ok here it goes....I have an Emperor angel (Juv) which is starting to get white blotches/spots on him – no sign of viral infection or growth or tear or anything, just blotches of discoloration. Last time this happened on another emperor, it died a few days later. The other thing that it appears to be doing is going up to other fish, like a small butterfly and even a dog face puffer (all fish are docile in the aquarium and none of them fight) and they both rub up against each other and flap their fins with each other….any idea what this is (again, last time I saw fish doing this they ended up dieing on me)?????
I've also noticed a cuople of other fish (percula clown and blue tang) scratching up against live rock - guessing ick, but no sign or trace of it....??
Here is the current specs:
Food: Spectrum Premium A+ Pellets
a. nitrate – 5ppm
b. nitrite – 0
c. ammonia – 0
d. PH - 8.23 – 8.30
e. Specific Gravity – 1.021
Water Temperature: 77-79F
Pre-drilled on both sides
Sealife Systems Wet-Dry filter
(3) chemi-pure carbons
Lifeguard 8watt UV
sterilizer (switching to 40watt) – currently running with dedicated RIO 1700 pump, sucking from the sump going back to the sump - at roughly 350-400GPH
Mag-Drive Utility pump model 18 (1800GPH) used for both returns
Aqualogic 1/4HP Chiller
Any help would greatly be appreciated – thanks in advance.
