So I have been so busy the last few days that I haven't been paying much attention to what's going on in my tanks. Other then regular feedings. Well last night I went to my angel tank and couldn't find my other angel. The one swam up to me as they both usually anytime I'm near the tank. I looked everywhere in my tank ... Nothing! Finally my bf found her... Well what was left of her. Which wasn't much. Her poor little scull and spine! Picked clean of everything! I hardly could see it! my poor fish! I have no idea how she died. Water was good I fed them as I always did. I feel aweful for not noticing. I did notice that my clown loach has been much more active and about.
