mph84,

To Reef Central
can you provide more information on the clam itself? size, where you picked it up from, etc. it sounds like it was an unhealthy specimen from the start.

What are the smallest clams? I don't have the biggest tank but saw a clam for the first time the other day in person and I gotta have one now. If I can find one that won't get to big.

mastershake72 · 01/29/2010, 02:35 PM

Crocea clams are the most common and will stay quite tiny, I doubt they will grow longer than 6"

TNTFISHY · 03/06/2010, 12:30 AM

Sorry for not reading the entire thread, but the first post said T5's are kind of dicey if you are going to try Croceas. I will soon receive a ATI 6x24 watt Sunpower. I'm thinking it'll be about 20-22 inches from the sand bed. Crocea thumbs up, or down?

ezcompany · 03/08/2010, 06:40 PM

T5s are "dicey" only if you have a low quality T5 system.
Most systems nowadays have great reflectors built into them with a super efficient and strong ballast for high output. How long is your tank? My general rule of thumb is, the clam cannot be deeper than your bulb length.

TNTFISHY · 03/08/2010, 10:20 PM

36 long, 18 wide, 21 tall. I have a 3-4 inch sand bed though. Thanks for your input.

ezcompany · 03/15/2010, 04:07 PM

i'm sure you will be a ok

post some pics!

a9reef · 03/16/2010, 08:52 AM

great info!

Psionicdragon · 04/14/2010, 10:49 PM

Are there any pars that you can provide on what these clams need instead of the type of lighting?

Navyblue · 04/16/2010, 09:45 AM

My tank is 12" tall, I have no intention of keeping a clam in the short term but I can't rule out the possibility sometime down the road. Would 4x24w T5 be sufficient for a crocea or maxima? I would probably go with the following bulb configuration:

- ATI Sun Pro
- ATI Aquablue or Blue Plus
- ATI Blue Plus
- UVL Super Actinic

I don't really have to put the clam at the bottom, but I don't want them to just barely make it with the lighting either

Thanks.

TNTFISHY · 07/12/2010, 08:58 PM

Update: My Crocea is doing great, and I just added a Maxima(I think it is).

DanEnglish · 09/30/2010, 01:23 PM

I currently have a approximately 18" giga at the bottom of my 110g tank (30in high). The lighting is 4x110w VHO, two 10k, 1 true actinic, 1 actinic combo of some kind. I have only had him about a week. He opens up fully, looks great, secretes what looks like mucus (heard this is OK) with some excrement like particles in it, and generally seems healthy. He is on the bottom of the tank though, so I am wondering whether the light is really enough, or whether over time he will slowly starve due to lack of light. Please let me know what you think.

DanEnglish · 10/17/2010, 01:04 PM

here is an update, after 4.5 weeks under 440W vho at over 24" depth, with Calcium over 420 I have 5mm new growth. looks like this is a good setup for the Gigas

Fer21 · 12/29/2010, 10:57 PM

Do you think that a máxima clam can thrive under the stock light of a max 130D which aré 2/55w t5???

Thanks

moliken · 12/30/2010, 07:37 AM

you have an answer in the other posts about this question. the majority opinion is no. the majority is correct. if you want a different answer, just to satisfy yourself, then just ignore what's been said in the tridacnid posts already and buy the tank. 2 55 w t-5's are not enough! and how they are 55 watt is a bit odd to me, as on a 65 gal 36"tank t-5's are 39 watts. the one you speak of is 36 gals?

I've had my maxima under a 4x24 for about six months now. He's 14" below the surface, seems very healthy and growing very fast. It's a fan-cooled TEK with good bulbs.

The aforementioned Maxima appears to be thriving under about 225.

anaya · 02/28/2011, 12:45 AM

okay I've read this entire thread. I am interested in a crocea for my 30gal. Still a bit confused about the T-5 issue that seems to be going back and forth.

depth to sandbed is 14"

light is a Nova Extreme SLR T-5 30" 48 watt

I do not own a PAR meter so can't provide a reading at SB

Is this possible? If not would a 70watt viper added to the above spotlighted on clam work?

the clam will be a little above the sand and hopefully, you will move it up on your rocks after a couple days. if possible get a better t5 fixture and sell this one. it's a better solution than the viper. they do make a 4 bulb for a 30 gal tank

studentdriver · 05/08/2011, 06:15 PM

Will Maximas do alright under the newer more powerful LEDs like the AI and Vertexs?

moliken · 05/08/2011, 07:45 PM

short answer is YES! i have numerous maxis under my ai's, which ive had four months. clams seem to love it. 3 clams are less than 2 months in the tank, the rest are all prior to the ai's under t-5's. don't know anything about vertex.

snowmonkey · 05/17/2011, 01:52 PM

Thank you this is very helpful

What intensity are you running your AI? How deep is your tank? I have AI and am considering clams.

i have my 3 ai's at max intensity only from 11:30-3:30. the rest of the time it's less. from 10:30-1130 and until 330- 5:30 its about 60-75%. have had the lights since dec. no tragedies. tank to bottom is 20" but clams are at different heights, based on their needs. lights are 12" above waterline though. clams would love the lights.
do you like the lights?

AC2020x · 07/31/2011, 08:48 AM

I am making a cree DIY set-up over my 29 gallon tank. I think I am going to put a clam under it.. this thread has some good and helpful information.

I'm just not too sure which clam to get yet?
