Blue Maxima vs Ultra Blue Maxima?

[dougisom@hotmail.com]

Is there a species difference between the two (Blue Maxima vs Ultra Blue Maxima), or is my vendor just separating the Maxima's based on blueness and charging 30% more for the so called Ultra's?

Thanks,
Doug

The vendors are buying them in different prices too.

There is no species difference, the only difference is the amount of blue-green on the mantle.

Thanks for the info. If I purchase a 4-5 inch maxima, will my normal 5 teaspoon per week phyto tank feeding (150 g) be sufficient. I have adequate lighting, 250 MH 20K and VHO Actinic's and VHO 10K's. I have heard that smaller clams, under 3 inches, have higher feeding requirements
