are they compatable with shrimp, hermit/emerald crabs? do they need low flow? any fish cause problems? how do you know if they are healthy when you buy them? any signs of a clam that isn't well, other than it being closed up?
 
i've never had a problem with shrimp, hermits or emerald crabs with clams. fish would depend on the fish you have, you should list them as well as any fish you intend to add later.

its not a good idea to add a clam to a tank that isn't fully matured (at least 6 months of stabel water conditions and in the correct range)

as for checking the health, you need to look at mantel extention as well as reaction to light. passing something over the clam and causing a shaddow the clam should retract in responce to the shaddow.

Also be on the lookout for those little white snails near the 'foot'. And while you have the clam upside-down, make sure its 'foot' is intact. It might look "shredded" but still be OK. If there is an obvious hole where you can see into the clam, don't buy it.
Also be on the lookout for gaping. If it looks like its shrunken into its shell and its "mouth" looks like its yawning, thats bad.
 
Of utmost importance before buying is that you have proper lighting for clams....what size tank do you have and what lights?
Best of luck!
 
I have a 90g w/ 30 sump. Right now I have 4X65 watt pc, but I'm getting a 175w mh and 110 vho setup next week. For livestock, I have 2 percs, 1 tang, 1 royal gramma, 1 lawn mower blenny, scooter blenny, and a chromis.

This tank has only been up for about 3 months, but I imported almost everything from a 55 setup from before, excluding the substrate.

What is a foot? What should it look like?
 
Sounds like you're off to a great start! With 175w bulbs make sure to put the clams up high in the rockwork, close to the lights! best of luck :)
 
the foot is the bysal thread which is what the calm uses to attach it's self to something.

as for your lighting it really depends on the type of clam your getting. seeing as it's your first ever clam i'd recommend a squamosa which can be kept under your lighting and safely kept on the sandbed. trying to put a clam up in your rockwork most often results in the clam trying to move and falls causing damage to it's self. also a derasa would be a good choice for a starter as well, just make sure you get one at least 3" in size.

I agree....a squamosa or derasa would be a good start.
Also, there are fish that will cause problems for clams...what kidn of fish do you have?
 
D'oh...I knew you had listed them...sorry, I forgot.

You should read Daniel Knop's "Giant Clams" It's the "clam bible" and will benifit you and your future clams greatly. It's the best thing you can do before you get a clam.
 
The bottom of the clam, when its closed, has a rounded gap in the shell. There is a white "organ" in the gap. The bysall somethin somethin. It is an organ that can extend pretty far. It lays threads like a spider and attaches the clam to rocks. Its also how the clam scoots around when its unhappy with its position. When the dude in the LFS or the collector in the ocean rips the clam from the rocks, he/she can tear up that organ. If you're careful and cut the threads gently with a sharp knife, the clam will be fine.
