Thanx will the shell look fatter?

when clams grow they lay down a new layer of shell to the intire inside of the shell. so yes they may look "fatter" by a millimeter or 2

okay thanx again. the best way I can explain it is.... when I first got him he looked like this \/ now he looks more like this ( ). Also how fast do they grow? I looked at him tonight and I can see on the very top of his shell is very bright white around the top edges. I have had him for almost a month now so if he is growing that is a real good sign right?

yes growing is a good thing.
Croceas are the slowest growers of the T. clams. as for an exact # for there growth, its hard to say, each clam is different. maybe a 1/4" per year

I saw a huge one at upscales I guess it was at least 18" or more and took up allot of space in a tank.
I wondered why it has areas where I can see no color patterns its just white like it was flaking off in areas?
I was told it does not need 100 percent coverage to get enough light but that looks ugly and not the first time I have seen this on large clams . Has anyone else seen this?

James Fatheree told me it was some kind of infection that killed the zoox in small areas of the mantle but didnt seem to do any harm to the clam.
he said he saw lots of wild Gigas with these bleached out spots

okay I have another question... I have been feeding my baby 1-2xs a week with phyto using the coke bottle method. I have acouple questions about Iodine and strontium. Would I be able to dose this the same way or should I just dose the whole tank? also what are the best products and tests for these?

i wouldn't dose either. if you do regular water changes you will provide all you need. most foods contain iodine also.
also i would just feed the tank the live phyto. clams are primarily photosynthetic. they do filter feed but they do this slowly all day long

okay thats what I have been doing. I dont add anything except the phyto. I just wanted to make sure that the water changes was enough. also when you dose the whole tank will the carbon suck it up?
chris&barb
Reef-Geeks
carbon and your skimmer may remove some, but thats only if it go's into it. i wouldn't worry about that too much, some or most of it will stay in the tank long enough.

Actually feeding the tank any phyto at all is unneccessary and is a source of phosphates. Clams will do just fine with NO feeding what so ever as long as they are around 3" long.

any food is a phosphate source. you will get into trouble with any food if you over feed or have inadequate filtration. the size rule is very vague, you can have a Crocea that is 5 years old and only 3" and a Gigas that is 1 year and 3". many people have gotten small clams and never feed them and they did great. i dont feed my clams, but i dont see anything wrong with doing it if you like.

Mine is about 2-2 1/2". I have cut back to feeding him once a week just this past week. (using the bottle method). I keep up with my water changes and I usually do my changes the day after I feed him.
