Do I need cuttlefish bone?

[trennamw]

If I have crushed coral in my tank do I need cuttlefish bone? I have extremely soft water which I do supplement with flourish equilibrium too.

I think it's fine, this guy has grown a lot in a month and the shell looks really nice from what little I know.



Last month.



Today.

About 1" of shell I think.

His shell looks really good to me. Nice set up

Thanks! Not bad for mostly fake stuff! And glad to hear the snail looks well.

Nope. Either crushed coral or cuttlebone works. Both together won't hurt anything but it won't necessarily help either.
