Lunch, I agree, you need to stop putting your tank down. It looks really nice. When it is your own tank you don't appreciate it as much as others. I am the same. When I look at my tank I see that small patch of bryopsis here and there before I see the new growth tips on this or that coral, etc... You don't know what you have until you lose it. I think we can both relate to that, having suffered full tank crashes. I look back at pictures of my old tank and wish I could have it back... at the time I didn't think the tank was all that great.
I think your clam looks ok from my end.
As for the bryopsis, talk to Grant and see if he can get you a small sea hare. He is going to try to get me one on his next order. It will have to work to get all the bryopsis in my tank but if that does happen I'm sure I can trade it around the club to keep a supply of food for it. I'm sure you could do the same. Grant has a couple sea hares in his tanks right now and they made short order of his bryopsis.
