Looks awesome. I just did a 55 to a 75 upgrade. Used the same sand, water and LR. I lost my algae blenny though the new tank was so clean he only lasted less than a week.
Your tank looks awesome. I'm scared to add a nem but I want a small red bubble or something just for my clowns to host because this past weekend they're hosting my 5 headed torch and it's pissing him off lol.
