Seems to be doing just fine?!!!
I didn't know that once they attached to a rock that they could still turn around?! I have groups of lights in my hood that come on in sets- each one brighter than the last. As they turn on, the clam turns to face the direction of the brightest lights. He moves in a 45 degree arc each day and back each night :splitspin
(sorry for the bad pics- can't find the tripod)!

For your information, according to my mom who happened to be in Solomon Islands when a giant clam study was conducted for the village clam farmers about 6 years ago, the survival rate largely depended on how well the byssal attached. The survival rate was up by 40% when they were well attached properly. Sand bed is a very bad substrate for the clam to stay in. Rocks that are hard to melt by the byssal's acid were also bad choice. The yield was up to about $200 from around $50 per case of babies provided by the government.

that tank is looking great!

Tech, the hippopus clam have no color they are very dull. but thet are great for eating nitrates in your tank. i keep 1 in my 30 gal. and 2 in my 90 ga. and never have a problem with nitrates.

CC I've heard conflicting reports on this. many people say that the clams do not filter the water enough for 1 or 2 to make a difference in the water quality. how many clams do you have in your tanks, and how can you be sure it's the hippopus making the difference? if I wanted to add some to my 120, how many and what size would be most effective for no3 consumption?

In my experience, none of the clams are easy...but I while I agree that derasa is the easiest, I would put squamosa just after it...followed by hippopus, then at the end with maxima and crocea as the hardest...no experience with gigas. I have found that derasa, squamosa, and hippopus prefer the sand bed, maxima and crocea the rock work. But its hard to get them to agree to a spot...they tend to hop off. They definitely should be started on the bottom before moving up, I prefer a rock or old coral piece with a depression in it for attachment. That said, I will no longer try maximas or croceas, my PC's don't give them enough light. Hippopus is least attractive, mainly because the mantle doesn't extend as it does in Tridacna's.The main clam pests are Pyramidellid (sp?) snails, occasional other snails that seem to suddenly appear out of the rockwork when a clam goes into the tank..they will find the clam whether on rocks or sandbed. Bristle worms will congregate under the clam, but leave it alone if its healthy....if it dies, they make very short work of it, leaving people to believe that the worms did the clam in...Take care, Eric

Jhale, i got my hippopus clams just over a year ago and after getting a great lesson on these clams from Barry one nite while talking with him on the phone i took his suggestion and added the amount of hippopus clams that he said i should add to my tanks. after about the first month that i put them in my tank i have not had even a trace of no3. as far as the list that i posted that comes stright from Barry, he keep's stats on all of the clams he ships and after shipping 10's of thousands of clams these are the results on how they fair.
