I think I found the problem of all of my fish dying. Well, I did water changes, bought chemicals, and medications, and every one of the Electric Blue Cichlid fry, about 100, died. All of them. I am so sad and pissed off. They were about 6 months old, and had a lot of work, dedication, and inspiration in them. Gone. Well, today, I was in the process of emptying the fish tank, and I found thousands of small, pinkish like worms that were as small as a human hair, about 3/4" long averagely. They swam around like eels, or snakes, but were just tiny, and like a pink color...? What are these little bastards that plundered into my tank? Whatever they are, they are dead now, since I poured bleach throughout the tank. :WTF:
