Looks like it is starting to open up:). How big is it? generally speaking, you might expect to target feed in some way if it is smaller than 3". 3" is just a general guideline, though. Nice clam:).
That is a great looking clam Chelsey... I had one just like it until some Kalk paste fell into the hole while I was killing aiptasia.....I almost cried my favorite clam and it was all my fault.....I think you will love it once it gets settled in......I want first frags.lol
