Another thing to remember about clams...They can get huge and some get huge fast. My gigas has already grown over 1/16 of an inch, in only 2 weeks... I can only imagine what he will look like in a year or two with growth like that. I have a 37g now and I am certain he will outgrow that in a few years...So far though he is doing great under my t-5 lighting. Heres a pic of the big guy...
