Thanks for the advice guys, I guess I am being overly paranoid about this 1st tank of mine! I'm having such a time with the cycle itself, I'm not even sure I've studied enough for fish. I will just let the tank be & exist naturally. I tell you, the smell of that shrimp was almost enough for me hurl- it just killed me to see all that funk crawling all over my beautiful tank! I 'spose this isn't the prettiest stage of SW! Thanks again!
