Clam troubles

[Nebthet]

Add me to the list fishytime, as you know. I have had clam issues too.. I lost all four of my clams. two teardrop maximas and two croceas.

There were no symptoms from the clams until they were too far deteriorated to do anything about it.
Something went at them from the bottom and sides eating away at them from the foot or flesh on the side when the clam opens. T
Their mantle on top would open and close like normal, as well as have full extension. No gaping, until the day of full deterioration when you could see a huge hole right through the side of the clam down to the bottom, but even then, the mantle is still mostly extended, but you can see all the muscous and what not out of the area that is disolving away.

No pyramid snails, no bristle worms, hermits or other snails on it until the day after the mantle stops opening at all. Then they go after it. (I only waited that long for the one clam because I couldn't remove it from my system without my RBTA being dishomed.

The only indication I had of anything wrong in the tank was how my corals were reacting. My blueberry encrusting monti lost it's color very quickly as did my purple passion. My Pocci kept it's polyps in and xenia was all wilted and closed up looking.

Test kit parameters all came back with nitrates, nitrites and ammonia at 0, ph 8.4, dkh 8, sg 1.025, calcium 420, magnesium 1350.

All other corals were acting just fine, even the anemones had no issues.

Within less than a week after the death of the last clam, a 10% water change and swaping out the chemipure for new stuff, all my corals are back to normal, and the colors of the ensrusting montis have come back in greater brilliance than they were before the deaths and are growing faster too.

Had I not been paying attention to my other corals I wouldn't have known there was something going on with my clams until it was too late and they were all polluting the tank at the same time. With the exception of the one, I removed all the others before they got the chance to hit full deterioration. FW Dippingg also didn't help these clams.
