Hello. I am new to the hobby. I have a blue-green chromis that has a white spot up near the dorsal fin. It showed up first this morning. I have had him for about a month. I don’t have a QT and fear I am about to see the consequences of that… he has been swimming around and eating fine. The tank has a gravel/sand bottom and live rock. There are two clowns, a royal gramma, a mandarin goby, 5 snails, a cleaner shrimp, and another chromis in the tank. The other chromis doesn’t have issues. There is also a god of war zoa and a type of hammer coral.
The tank is a 40 gallon aqua top. It has been running since April.
These are the measurements as of today:
Temp - 81
pH - 8.2
Ammonia - .2
Salt - 1.025
Nitrates - 10
Nitrites - 0
Alkalinity - 8
I turned the heater down to try to bring it back to 79 and am going to do water changes to bring the ammonia back down. The ammonia read 0 at the end of May.
I have tried to find out what is wrong with the chromis. Is it ich? Or uronema? It’s not red at all. Maybe another fish took a bite at it or it scratched itself on a rock? Would I be best off just saying goodbye to save the other fish?
Please help. Any advice would be greatly appreciated! I tried to get the best picture of it and to give a sense of the overall tank. The spot is right at the base of the front of the dorsal fin.
