Worried about my tiger conch

[DustinDec]

I introduced a tiger conch about a week ago and he climbs all over the tank. I’ve been over feeding variable frozen food, pellets and flakes. Activity wise, very active, but I noticed his shell was dark and had a red spot. Normal? Feedback is appreciated!

Looks like a small buildup of coralline

If it is active and eating I should not worry to much

Algae tends to grow on a conch shell.
