A Quick History:
150G
Amm/Nitrite - 0
Nitrate - ~15
pH - 8.2
Temp - 80F
Tank has been setup since early October and was fishless cycled. Added first fish 11/2.
Current stock
7 - Aulonocara Hanbaenschi
5 - Maylandia Esterae
1 - Nimbochromis Venustus
4 - Bristlenose Plecos
Yesterday, I noticed one of the zebras had a 1/8 white spot on his side, just above the anal fin. Tonight I finally got a chance to sit down and observe the tank for an hour or so. Things I've noticed.
a. Infrequent, but noticeable flashing amonst all africans
b. Both Male zebras (2) have white spots (skin is white, not something on skin) on both right and left sides. There were a few loose scales. No other fish have any noticeable skin damage.
Things that have changed this week:
a. Added the 4 plecos
b. Both Male Zebras have had significant color changes. Their fins have turned a light blue, which I assume is going to be their adult color.
c. Both Male Zebras have stepped up their agression towards the females and seem to be interested in breeding. Made me wonder if white spots might not just be agressive damage.
d. Did 30% water change tonight, same as every Saturday.
Anything you would do right off the bat? I can't seem to find anything that matches all the symptoms, however, the flashing behavior has me concerned about some sort of parasite. How long would you "observe" before taking medical or chemical action?
Thanks...
