We noticed a few weeks ago that our Bamboo Shrimp was hanging out on the heater. We checked on him a day later and he was ghostly pale, with what I assumed to be, at first, a cyst of some sort, but it turned into what looked like a blister (I posted this previously).. He is now back to his bright red color and eating normally. The "blister" has gone away, but there is now, in place of it, a gaping hole in his side. It doesn't look very pleasant, and I just want to make sure he will be okay??
