6~When is the last time you did a water change and vacuum the gravel? How often do you do this? How much water do you remove at a time?

1 day. I floated the bag for 20 minutes, added some water waited 5 minutes added more water from tank (rinse and repeat for 45 minutes.

No

9~What kind of food have you been feeding your fish, have you changed their diet recently?

TetraMinBaby.

The mollies are swimming fine, eating fine and playing. Completely normal behaviour no visible problems other than the clamping. No fin rot, gill inflamation and they are too young to be pregnant. The tank is a tad bare. It has treated bog wood, 2 orniments (one an open pagoda), 2 plastic plants, stoned, sand substrate (play sand washed to death!), 4 moss balls. The filter I use has a spray bar and is pretty fast flowing. I will be going to LFS in an hour so if I need anything while I'm there like medication I need to know now! lol. I am going to buy some live plants so I'm hoping this will help and it is just stress or something from lack of hiding spots. Any help would be really appreciated.
