Hallo Deepin peat,
I see already that I have more shrimps now in the tank, the seaweed is almost eaten from the root! 😉 …
By the way, if I see excuvie, I take them out 😉 but I never had problems with that.
And my god – you have Battle-Paros 😉 (perhaps some youngsters?) 😉
In my tanks with Spaerichtys I can see that they ignore the shrimps (but not the fine shrimp pearls if they can get it…… 😉
My Paros seem to ignore them till now too 😉
