Well, this is not what I was expecting when wanted to know about a crabby crab. I, quite honestly, know almost nothing about keeping a salt water tank. This is a school sponsored tank and, sadly, our person moved recently. If those corals need to go, is there anyone that would be willing to help with this when we are out of social distancing restrictions? Maybe when the tank needs to move again in the late summer? I definitely don’t need to accidentally poison myself, family, or my students.
