wells brain losing color


New member
I have had a wells brain for about 2-3 months and noticed today that it seems to be losing color and also has been moving toward the front of the tank. When I got it the color was a darker green and today I noticed it is more neon green with white between some of the green. I don't know if it's getting too much or too little light. I don't target feed it anything and don't know if that is an issue. It is on the bottom of a 150g reef with 6-80watt t-5 lights. All params are in check but phosphates are a bit high (I've been dosing vodka for that). Any ideas?
