Coral banded shrimp derp
I got a coral banded shrimp a couple of days ago (small) and this morning found him stuck in the intake screen of the filter. One of his big arms went through the hole, but the rest of him was too big to get sucked in. I turned off the filter and gingerly pulled him out. He was immediately active and I don't see any missing parts. The big arm that was sucked in looks a little tweaked but it may have been that way before, I'm not sure. My question is, are they intelligent enough to know not to go there any more? Or do I need to come up with a creative way to dissipate some of the suction by adding surface area to the intake?
Another side question, do coral banded shrimp use their big arms, or are they just for protection/posturing?
