ok so i want to get a clam for my 3.5gal pico with LEDs
i know that the clam will eventuly ( and quickly ) become to large for this tank
which is ok because i have a 20gal long that it will go into
the reason why i want to put a clam into the 3.5gal is for a contest
so when the contest is over ( in 3 months ) i can move it to my "bigger" reef

the clam i found that i want is a crocea
as seen here ( a little down the page ) http://www.michiganreefers.com/forum...ap-sooner.html
those 3 are 40$ and about 3-4"

so i just want your opinon on getting one in this tank and what things i need to watch out for if i can get one

thanks for your help
Ryan
