Question about derasa attaching to bottom glass?

[BriDroid]

My new derasa is sitting on about a half inch of sand. Of course it has attached its byssal threads to the tank bottom under the sand. My understanding is that this is fine and once it gets more size will release and just sit there using up its mass to stay in place.

I posted a pic on Facebook (I know…) and someone posted a reply and said how bad it is for them to attach to the bottom glass???

It's perfectly fine to attach to any solid surface. As it gets bigger, you may need more sand so it's not resting directly on the glass, which isn't good for long term hinge health.

Sounds like you have the concept down perfectly. My Hippopus occasionally attaches to the bottom. Just as long as you don't inadvertently roughly tug on the clam while it's attached it's all good.

Do you think not enough sand is a cause of or contributes to broken hinges on derasas? Asking because I lost my first derasa to a broken hinge and currently have two and would like to prevent it if possible. Mine are currently attached to frag plugs placed in the sand under the clams.

If their shell is bouncing around on glass, then yes. The larger species are found on sandy bottoms mostly, so it’s better to keep them on a” cushion” of sand.
