THE OFFICIAL TRIDACNID CLAM THREAD

[MikeTR]

Now thats what Im talking about. Super healthy big floppy mantle. Very nice wild clam with lots of unusual growth on the shell. If you lived closer I would nap it from you.

 

 

 

 

 

 

 

SWEET!!! Yes I I see it mid left. Your tank looks great, but I may have to call the cops on you for having that powder blue tang in there. He he heeeee!!

 

 

 

 

 

 

So far so good...

They always are. Clams are one of the few reef critters that can look perfect one day, and be completly dead the next. Sometimes completely gutted out without explanation.

so far it out lasted my Derasa, but tank was too young for a clam at that point I think. I didn't have any choice but to move him over as the other one was getting shut down.

 

 

I could tell something was amiss 2 days before his shell was empty. Just wasn't opening up as far, and then gone.

Glad you think my baby looks good Zeph! Hoping to get it a sibling in a few months!

NICE!!! Not long ago Creceas where the most difficult to keep. I dont know why but they appear to be easier these days and Maximas have displaced them. THanks for registering, Nice new growth !!!!

THank you for the update. Please let me know if you feel the addition od carbon and gfo has had an effect on your clam. I like PO4 removers, but am weary of carbon. I do run a very small amount of carbon just for shitz and giggles.

Started him off on sand bed and just recently raised him about 4 inches into a crevice in the live rock

to try and get him a little more light. Never gapes and his mantle is slowly lightening again.

 

Deceased. Vacation casualty . . .

DOC level estimate? no idea
Do you skim? yeah, name design iii
Do you run carbon? nope
Do you run GFO? nope
Did you ever freshwater dip the clam? nope, but it has had a few h2o2 treatments.
Are you seeing new growth? yes but only a little
Calcium/Alk Method? none other than twice weekly 100% water changes with nsw
Where and when did you get it? lfs on march 15th 2013
Do you purposely feed ? i feed my tank very heavily with clam filter feeder powder by D-D and with korallfluid by JBL and on water change days i throw a full cube of frozen red plankton into the tank(3 gallon)

 

 

theres the whole tank to show position of the clam in the back right on the base.

ignore the half dead acro it came from my nano which crashed with a wonky heater

does anyone here know of anyone else that has kept a clam in a 3gallon pico? and how long did it last?

THis is exactly the type of post I was hoping for when I created this thread. I am so glad to see you have been keeping a Maxima in a 3 gallon successfully. We have had so many inquiries weather or not it is possible to do that, and you have proven that it is.

In all honesty your clam looks a little pinchy, and you have reported that it has had fresh water treatment, so there was cause for concern at some time, but it still seams to be doing well. Let it be though. I like what you have done. Please let me know how this clam is doing in the next few months, this is a very interesting case to me. THanks for posting!!!!

Sweet 1st grade blue maxi !!! Looks good. Let us know how it does in a few months. Seeing as you are running most nutrient removal systems - carbon, PO4 remover, skimmer.... and Led's alone, this is an interesting situation. THanks for posting.

I will work on getting better pics

[icedearth15324]

So I have to admit, these things get addicting. It doesn't help that one of my LFS has beautiful ultra maximas for like $60 each. Next time he gets some blue squamosas or any croceas in, I'm going for one.

Oops, my bad.

[jedimasterben]

Oops, my bad.

CPE contains a minuscule amount of GFO (actually, less minuscule and more pathetic for the price lol). You'd be a lot better off to purchase carbon and GFO separately to use (Phosguard is a better choice if not running in a reactor, though).
