Clam Mortality Part 2

[fencer]

I was wondering if the admin people could setup a poll on Clam mortality. I have seen a number of post regarding the sudden demise of there clams without apparent cause. I would lke to see in this form or something similiar:

How Long have you had your clam before it died?[list=1]
1. 0 - 6 months
2. 7 - 12 Months
3. 1 to 2 years
4. Still Alive(2+years)

I've only had oldest clam a year and a half but it is still alive and doing well so I didn't vote

Unfortunately I've had all of the above. I've had clams die on me in the first 12 hours. However I answered with the most optimistic interpretation and that's looking at my oldest clams which are now somewhere in the 3 year mark. Actually my oldest clam, I've had for 3 years, but it was from someone else who tore their tank down, and I'm not sure how many years HE had it, but it was at least 1 year IIRC.

So, it's possible that some will hang on. Unfortunately they're just incredible senstive things, so it's very easy to lose them. But some do rather well.

4-5" Crocea for 13 months. Seemed well, as happy as a clam (had to), 24 hours later dead.

One thing I'm wondering about did my alk levels have an effect? NSW is 7dKH, I'm running 11dKH.

Congrats to all who have had clams survive a one year...my hats off to you. IMHO getting a clam to survive is harder than SPS. I trying to get a handle on these clam deaths. I have read some of the most experienced reef keepers have reported sudden clam death. So tank quality is probably not the number one cause of death. I wonder if it has more to do with the age of the clams. Older clams may have more problems in adjusting to reef life. Also the number of crawly inverts in reef tanks are much higher may also contribute to this syndrome.

I have had a teardrop maxima for well over 2 yrs.

Oldest clam on the right, had it going on 7 years now, was just 3 1/2" when I got it, will just fit in a 5G pail now.

My clams range from 3+years with me until around 2 months. I've only ever experienced two natural clam deaths (e.g. not eaten by something in the tank), and have experienced a total of 4 deaths since I've been doing this, two to random death in 24 hours, and 2 to a lunare wrasse snapping and going crazy.

Catherine was the clam(s) that expired were they 3"+ or smaller?
Lando and Catherine: are there a lot of crabs in your tanks, how about flat worms? There is another thread on the forum : that they were feeding clams by target feeding. I have never done that but do put phyto in the tank every 2 days but never targeted the clams. I wonder if the clams were not getting enough food. My clams were sitting on bottom (16in, 300watt MH's) is that enough light. Qunister...nice clam...his clam seems to fit my suggestion that smaller younger clams can adapt more easily to new reef systems.
