How to indentify different type of clams

[jc85]

Hi All Guru,

I am planning to start trying some clam once I get my lightings upgraded to T5. At meantime, I've been reading up on clam info. However was not able to really understand how to indentify the various type of clam.

Any advise please?

Thank u

t5 are not good enough for clams.. i suggest u get to upgrade to MH before u try on clams

[jc85]

I have a shallow tank (15') and gona have 4 tubes in a width of 1.5ft. I was thinking of trying out the Derasa Clam (hardy?) or the Squamosa Clam (lesser demand on lightings compare to others).

Any advise how to differential between the various type of clams. I'll still need to know these even if I have MH lightings?

Thanks

[ah^siao]

it is best if u can afford MH la.. hmmm such a shallow tank.. i think T5 might do the job.. but be sure to place the clams high up and also get the lesser light dependent clams

[pospeh]

The derasas and the squamosas are the least light demanding clams. T5 should be ok for them.

These two types of clams are almost always brown colored.

The derasa is small (about 3 inches). They dont have overhanging mantle and their shell are smooth.

The squamosas can get really huge. They have overhanging mantle and they have scales on their shells.

If you see green or blue clams, they are either the croceas or the maximas.

Thanks pospeh.

I'm I right to say that if the shell is smooth, it will be derasa clam. Does any other clam like the maxima also have smooth shell?

Eh derasa clam do have stair case like edges on thier shells and IMO definately not smooth

this is one of the biggest types of clams for your info

[jc85]

Wat's the standard size of squamosa clam we often find in LFS? 4"?

[AquaRa]

u have a shallow tank, need not buy metal halide. if u have metal halide, don't need to place your clam too high up, because it may be fried by the metal halide. another pt to note, clams may suddenly shut their shells with a great force, forcing water out. so if ur clam is place high up, the water will spill over, damaging equipment.

Oh Yes!

Doing extremely well

Thanks for the good specimen

The other one still available?

it is also squamosa?

[blueheaven]

to differentiate between crocea and maxima:

crocea-fairly smooth shell

maxima-REALLY not smooth shell

[pospeh]

The croceas are more rounded in shape, like an egg. Their byssal openings are also fairly large and round.

The maximas are more elongated in shape, like a papaya, and their byssal openings are longer and narrower.
