3reef / ClamsDirect Raffle!

what kind of clam needs the least light? and what would be enough light because I don't think I got that aspect covered as of yet!

 

A T. squamosa is the less light required.

 

Barry, is that just of the nicer looking clams we see crocea, derasa, squamosa and maxima, or does that include gigas, hippopus, etc. as well?

 

In order of light requirement, I would rate them from less light to most light.

Squamosa, Hippopus, gigas, derasa, maxima and then Crocea.

 

Barry,

Assuming Metal Halides and Actinics are needed for the Croceas, what lighting by type and in watts per gallon would you recommend for the different clams?

Thanks

 

IMO , I really I not look at watts per gallon per say but PAR.

No doubt that most clams do better in the long run with MH but have a lot of customers that keep Tridacnid Clamsunder PC and some under VHO. Again, IMO and observation, Maxima can do ok under PC if is less than 18". Brown or Gold Maxima require less light due to the brownish pigmention of their mantles rather than colored Maxima.

IMO, I think that Squamosa, hippopus, Derasa will do ok under strong VHO but again not in a deep tank.

 

Thanks Barry!

 

Great info Barry!

Gotta ask (since somebody will ) , which ones are good on sand and which will do well on rocks?

 

Thanks for the Contribution Barry,
Just make sure if it goes in the sand that you don't have them sand siffting Gobies in your tank, don't want the sand going into the clams, learned that first hand, LOL...

 

I second that, sure will clog the gills and then we know what will happen.

I place my derasa, Squamosa,hippopus and gigas on the substrates and maxima and crocreas in the LR.

When placing clams in the sand, I like to place a small pieces of shell or rock about a 1/4" under the sand so when the clam starts to bore, he will come in contact with the shell or rock and attach to that. A good way to also protect then byssal.
