Thanks! I'm pretty happy with how it's shaping up, to be honest. I've never done much decorating with my tanks before. :3
I did take off the rotted ends of the Anacharis when I pulled the bundle up, but I'll go through it tomorrow and see if anything else needs to be trimmed. I didn't want to hurt it by being overzealous.
I will keep assassin snails in mind, I did add in a trio of trumpet snails when I was getting the cories because I've read that they're good when you have sand, so it'd be a bummer to have those all end up being food also. I don't mind snails when they're pulling their own weight in the tank I was mostly just reacting to my surprise at seeing so many after I'd gone through and gotten rid of all the eggs I could find! I doubt I managed to get them all anyway, so I'll just keep an extra strict eye on how much I feed my fish in the future to stave off population booms.
