ID help

[cjtabares]

I bought this clam at reefapallosa, but thought they said it was a Maxima(I could be mistaken, I talked to a few vendors about a few different clams and could be misremembering), but looking at the id thread I would say it was a crocea. Also, it is attached to a plug(not glued), should I try and remove it, or just leave it as is? Any help would be appreciated.

 

[Mr. Mojo Rising]

It looks like a maxima to me. The crocea shell is smoother without the ridges.

 

[Miami Reef]

Agreed. Maxima.

Agreed. Maxima.

Ok, thanks. In the ID tread I thought it said the scutes could be on the crocea, and the mantle looks a lot like what they said most croceas look like. I am new to clams so I have no idea.

T. maxima, you can see the row of eyes and the papillae (those raised little bump-like protrusions). Nice color! There's not a lot of new growth, so it's been in subpar conditions, give it plenty of full spectrum light. You should see new growth within a week or two.

The shape of the shell, the coloration pattern of the mantle, the roll of eyes along the edge all pointed to Maxima. Maxima 100% sure

Oblong shell, and defined eyespots around edge of mantle. 100% maxima. Good luck!

What am I looking for on new growth and how much is good?

Is it these white parts of the shell?

Any tips so I can reduce the luck needed and have better success?

Here are some of my maxima clams. This is the ideal growth.

So maxima clams are collected in areas with 7.5dkh. they are filter feeders it’s best to keep your nutrients elevated. I’ve raise 2 clams from about 1.25”
I used to dose phytoplankton, but at this size they want light. Make sure they are not shaded.

Being a filter feeder doesn’t mean an organism wants higher nutrients (phosphates and nitrates).

Filter feeders want zooplankton in the water, and not necessarily nitrates and phosphates. Those are what photosynthetic organisms want.

People mistake this because in the home aquaria, feeding filter feeders results in higher nutrients, but that often kills the said organisms, which like lower nutrients despite requiring zooplankton in water.

Same can be said for clams which appreciate plankton in the water but don’t like too high nutrients.

In the ocean this is doable (low nutrient, high zooplankton) but hard in the aquarium

Also not to be confused with a dirty tank. My suggestion would be 10n and .1-.2P

Right, they would obviously use nutrients like all photosynthetic creatures.

But I would not keep them “elevated”.

I would just keep them at regular parameters.

And you said they need higher nutrients because they are filter feeders, that was wrong, which was the point of my post

My apologies for the confusion. I come from a time when the recommended nutrient levels were .03phos an 3-5n and that’s just dangerous for all forms of life (because of fluctuations) and would be worse for a filter feeder that relays on those forms of life

But that’s the thing again, filter feeders DON’T rely on those in the water column.

They eat zooplankton by definition.

Low nutrients is a more of a problem for photosynthetic organism.

Are you saying clams would live fine in 0N and 0p. I’ve collected hundreds of clams over the years and they were always more abundant in run off areas. Nutrients are the building blocks for all forms of life. Please ask yourself what do zooplankton eat?

You want to make sure there’s new growth on the upper margins of the shell at all times. I would recommend that you buy this book. Clams need nitrogen and phosphorus, so just feed your fish daily and you’ll be okay. If you want to dose phyto to “feed” the whole tank, great, it can’t hurt and will most likely help. Clams need a stable system with strong full spectrum lighting. Their nutrition comes from the lighting and do uptake nutrients from the water.
