Hippo losing color

[rj016]

Looking for some help. Noticed our blue hippo coloring had changed past couple days, which is about a week after rearranging some of the rock. No other changes. Lost all the lite blue on top half, now all dark blue with white areas on lower half and behind the eyes. Fish has been in this current 120 for 2.5 years thriving well, eating well, probably 5-6” long now.

I don’t see anything standing out. It looks like you have him on a good diet. The color shift may just be coincidental growth spurt same time as the redo. Just a thought
