Well he is still small. My fish run from the camera when they are small. Like the other person said info would help. What size tank, when you get him, his tank mates, water per, tons of stuff needed to know.
When I have her in a 30 gallons tank by herself. I change 40% water every week. I had her when she was one inch. Now she is about 3 inches. When she stress ,she turn really dark for about 5 mins and turn back to normal. But she eatting fine. The pink just start to come out alittle. I feed with gs, fbw,
Mine does the same thing except i get those dark vertical lines that cichlids get. It usually only happens when i turn the tank light on or when i go near the tank.
What's the temperature at? There must be something that is causing her to spook. When I got my horn it would spook like a ***** all the time. I found leaving the lights on majority of the day helped.
