As a x-mas gift to our selves, my wife and I picked up a 2.5ââ"šÂ¬Ã‚Â-3ââ"šÂ¬Ã‚ Maxima. It is residing in our 30 gal Oceanic cube set up almost a year ago. The 30 Gal is an upgrade from a 16 gal bow which we had for about 2 years. Tank parameters are pretty stable for a while with Calc hovering between 390 and 410, Alk 8-9. Amonia, nitrates and nitrites all 0. We have a 250W MH pendant with Gisemann 13K bulb. To acclimate the clam I placed it on the bottom of the tank on about 2ââ"šÂ¬Ã‚ of sand. Some questions I have: Should I place the clam on a piece of rock I start to slowly move up the rock work as it acclimates to the new tank and lightning? Considering its size how often should I feed it?
