Well I see that it appears that have a couple flat worms cruizing around on your clams. I had those damn things really bad not long ago. I used to suck those suckers out daily. Since I removed my dsb I hardly ever see them anymore.
On the subject of lights you have had recently, don't forget the radiums! Once you find the perfect light please let me know, I am due for lights in 4 months so hurry up
