Have a female that attacks and jumps every time I open the feed door or lid just about. Shocked me the first nibble it attempted while I was pointing where her pellet went which I have always done. But really made me jump when it jumped out of the water and tried to nip me when I wasn't feeding it. She wasn't like that until she got into a cycled 5 gallon tank, guess 2 gallons kept her from being wild. The other 3 are content with staying in the water thank goodness.
Thanks for the help on my betta, nice to know some care. LOL got a big laugh out of your Owner pic of Betta Evolutiooon in your tag. Changing out the horse troff water I looked over and saw one of my goldfish on the ground thrown out with a bucket of water no telling how long. It survived though years ago.
