I just want to say that I’ve helped John for a long time on live sales and at shows. He has been a close friend even longer than that. So even though I may be biased, I have personal experience with the clams he sells.
I’ve had nothing but amazing experiences. These clams have been in his possession for a long time (months-years). They are not wild collected, but are bred from a microscopic size. A 2-3 inch clam has been in a tank for several years. Clams wouldn’t survive that long if they were truly unhealthy. Maxima clams are incredibly sensitive to water chemistry/ph and lots of critters in our tank enjoy snacking on them. They have less ability to recover than sps, which might explain their protected/endangered status and the unexplained deaths you hear that comes from all clams or any other sensitive organism in a reef tank.
I have purchased 1000’s of dollars of clams from John. Unfortunately I lost them due to high tin levels in my water, as well as some other lps and sps (completely heartbreaking). They grew in my tank happily until my mess up. I have no problem taking ownership of my own misstakes and have made adjustments to try to prevent similar failures in the future. None of the companies that I lost animals from were responsible for my water quality parameters. I imagine we have all experienced losses in our tanks due to known and unknown reasons. I cannot get on board with the idea that clam mania is selling unhealthy clams or scamming people due to my own in personal experiences with 100’s of clams several times a year. I have no qualms buying more clams from clam mania now that my parameters are back on track.
I think it is reasonable to take all reviews into account, but do keep in mind, you will always hear more negative reviews than positives. just wanted to add my .02 to the convo.
