I had a betta baby I named Buddy that was such an odd fish. One day I noticed that he hadn't eaten all his food (freeze-dried bloodworms as that was all his mouth could handle, before I knew better) and so I grabbed my net to clean them out. This was probably like an hour later, as all of my bettas have been odd in that they like their food really wet. If I followed the two-or three-minute rule, my bettas would never get to eat. Well, I start cleaning the old food only to discover the little brat had been hiding food all over the tank in places I could not see without taking the lid off. I was so mad and so disgusted. I went here (how I got started here) and decided to get a snail to go with him. I got an olive nerite and added her to the betta tank as carefully as I could, letting her crawl out of the bag on her own and all that jazz. My ever curious little friend went to check her out like I knew he would. The snail touched Buddy's face with one of her little feelers, sending my "fighting fish" into a panic attack. He went zipping faster than a cheetah at full sprint into the moon rock cave and would not come out for over an hour. I laughed so hard, I couldn't breathe. He never went near its head again.
There is no such thing as an expert. Only more experienced than others.
