Today, I got some tetras. I'll have to ask what type they are in the morning. Anyway 3 days ago, my ACF Blotchie died. I have noticed my fish stay at the bottom at the back and won't go near the log that Blotchie used to sit on. I was wondering if they can smell Blotchie was there and still think she's somewhere in the tank, or just haven't got that courageous yet.
