I dont know much about clams bessides the i really want one, however 20% water changes daily would be difficult to manage for a system that size...

Any chance you can divulge the secret with the clams? I want to get one and currently have a cleaner wrasse in a 34g cube, so now I'm afraid the wrasse will nip at a clam if I were to purchase one and they are pricey 60$...

OH SWEET JESUS HELP US. No disrespect.. I think.

Just get rid of the cleaner wrasse. They were only telling me to do water changes cuz I haven't done one in a long time

I think you and me are beyond help..........and maybe a few others to.

Not yet, not up to this day. are you saying that all cleaner wrasse attack clams?

Of course not, simply teasing hence my envious green face. However many in fact do eat clams, most actually develop the behavior later in life.

Hey my cleaner wrasse bites my arm whenever I'm in there doing stuff so anything is possible.

Here is what killed all seven of the clams that I had collected over 5 years. Have you ruled them out completely? I rarely ever saw them on my clams, the species that I had must have preferred other snails. I would however see them all over the glass, sand and rocks during the day and night. Once I went clam-less and basically snail-less for several months they all disappeared and I haven't seen any in the last year.

Begin doing regular water changes, thats obvious. My other recommendations are to give them a freshwater dip, then remove them to a quarantine tank and do daily water changes on it with water from your main system. Replace the water that you remove with newly mixed saltwater. Then just wait and see if they improve.

The astrea snail in this picture is actually still alive and well in my tank a year after the clam genocide.

For nearly a week before each one died they would look like this.

I only have him for 2 months so that remain to be seen. But I do feed him very well and often, like 3 to 4 times per day and each time he eats like a pig with a huge belly.

I suspect that if I was feeding my tank every other day, he would definitly try to find other food because he's a real piggy.

If he ever go after my clam I will be selling him.

I haven't seen any of those snails in my tank. And today both of my clams are fully open and seem to have recovered completely. And they're both reacting normally to shadows and vibration
