Stocking question
 

I would like to get a clam for my 10.5 Gallon tank. What would be a good type of clam to start with?

I wouldn't suggest a clam in a tank that small. Clams are fussy and the parameters in a small tank aren't steady enough for a clam to thrive/survive...besides they get too big too fast. The clam will take up half the tank in a year if it actually does well.

What kind of lighting do you have anyway?

I have T12 URI VHO lighting 4 30W bulbs on a icecap ballast
