The fish looks completely normal other than this.
I have had him for a couple of weeks, since then, I have added 2 green chromis but they do not bother him.
The other fish are bigger and in full color, very healthy.
The water readings are tra 0 tri 0 amm 0 sal. 1.025
I feed him an assortment of hikari pellets, garlic soaked brine, and various flakes and plankton, he eats wonderfully.
Do you think he is just so submissive that he doesn't become colorful?
