Wow thanks guys! I was afraid that there was something wrong with my betta who has been in his new tank for two weeks and does the same thing when I go near the tank, even crashing into the walls to get away from me. Same thing Bass, you'd think I had beaten the little guy! Mine goes on a complete hunger strike when I give him flakes, so about a week ago I started to feed him freeze died blood worms which he seems to be eating well enough. I know it can be frustrating Fish, every betta seems to have a personality of it's own. I had bought my betta thinking it would have the same vivacious personality as my last betta, who used to love to follow my finger along the glass of the tank and was always a joy to watch; and was slightly dissapointed to discover a skittish fish that hid from me when I would approach the tank! We can only hope that they adjust! Good luck with your betta, hope all goes well!
