Aww, thanks both of you :) *hugs back*
Yes, I have a divided tank and since I have some free time today, I definitely am taking it down and bleaching everything in there and making a huge water change. I think I'm just going to stick with 3 fishies, 4 seems to be too many for me to handle lol. Please pray (or if you aren't religious, good vibes) that the bad luck will turn around!
