I finally found a clam

[gatorracer]

I hope this pic show up I am trying out some pic editing software...

But anyway I got a Deresa. I have about 7" from the water surface on a crevice I built for it. I hope all goes well just thought I would show her off.

Nice specimen. They grow pretty fast and get big. 8)

I dont expect an exact answer but when you said

They grow pretty fast and get big.

How fast?

Just a suggestion...pull it away from the Ricordia. It won't fully expand if it's touching a stinging coral like that. It looks like the mantle is actually retracted behind the shell right there.

Nice Ricardia and clam. It can grow like an inch a month, esp. for younger specimens. These clam can suck up calcium like sponge in water.

yah I agree with Matt, get away from those ricordias.. besides I would think the light intensity would either favor either then clam or the rics but not both at one particular location.

 

[gatorracer]

You know i never thought of that. I bet I have my rics way to high up in the tank. Thanks for the constructive critisim.

That is a very nice tiger stripe derasa. I second everyone else's suggestions. Derasa's are much more comfortable on the floor as well.

I am a little scared to put on the floor. I have about 4.5 watts per gallon and I dont want to see it wither away. Unless someone with experience thinks it will make it.

 

[Unarce]

What type of lighting do you have?

Because of the different types of lighting, the 'watts per gallon' method isn't used as much anymore. For example, you'd get more intense lighting out of 175 watts of MH as opposed to 192 watts of PC.

Personally, I've kept derasa and hippopus clams in my sump with just some actinic lighting, and they did fine.

 

[gatorracer]

6 X 65 watts PC's

4 of them acitic

2 50/50's

I think it'll be fine, but if you decide to keep it up on the rockscape, be sure it's placed securely where you don't end up having to reposition it from time to time.

Often times, clam losses can be attributed to improper placement.

Good luck!

Gator, small ones tend to grow pretty quickly. If I had to give a rough estimate, I'd say they can add an inch (or more) a year. I know that doesn't sound all that fast, but relative to most other clams, T.deresa is a quick grower.
