I went to reefapolooza NJ 3 weeks ago. I purchased a maxima clam. Really beautiful. I have a 220 gallon tank. Everything was great to yesterday when I noticed him not fully opening and 2 tiger conchs near him. I moved him to another side of tank. Today I woke up found a tiger conch near him and clam opened and dead…. Really mad. Tank includes
4 tiger conchs
1 schoal tang
1 purple tang
2 green chromis
2 clown
Who is the bad guy ? Please help. Need to understand why this happened

Sorry. Clams can be tough. My best guess is there wasn’t a bad guy. The clam died for some unknown reason and the conch was doing his natural cleanup duty.

Do you think tangs possibly attacked him ?
No. I don’t think any of those fish would cause a problem. I would be concerned about pygmy angels, but those aren’t on your list. Pyramid snails can be a problem, but you would have seen very small snails on the bottom of the mantle. Otherwise, clam deaths are hard to figure out IME.

Dying in 3 weeks depending on the size of the clam, generally indicates either a unhealthy clam, they take that long to die if not healthy despite looking good, or something in the tank killed it. Based off the list I think it probably wasn’t healthy to start, which can be nearly impossible to determine. However I have had tangs including purple pick at clam mantles once they develop taste for the slime. It seems unlikely here as you should have seen it.

A general rule I use is 2-3 weeks in an otherwise healthy tank to die is a clam with a problem, longer that time is something with the tank. With plenty of exceptions of course.
