Hmm noticed that recession on the large brain, some sort of damage maybe?
Other than that, this looks awesome! Quick question about that orange coral above the large brain in the picture, I'm assuming that's the orange lobo in your budget? Easy to keep? Aggressive? Curious because I think I'd like something like that for my tank (once it's up and running) but I don't want anything with crazy sweeper tentacles.
Again, well done!

Love this tank.
