Yep he will grow it back I had one for 2 years and it would fight with my red brittle star and would louse an arm and in a week or so would have a new one.
It's been 5 days and the one armed banded shrimp is still doing fine. No sign of an arm yet. I will keep watching him for signs of a new one and let everyone know if He does grow one.
Yes, the banded shrimp is growing back his large pincher. :clap2: I don't feel so bad now. I just hope he doesn't get mean like some people said theirs did.
