My fish used to be really cool and a lot of them would swim in the open water. I did a major tank remodel about 3 weeks ago and now EVERBODY is so scared of me. They all scatter and hide when I walk in the room. And nobody comes out for food unless I sit down and watch with the food in the tank for almost an hour. But even then after they start coming out one slight move of a muscle, a tiny vibration, the creaking of the floor, etc they all duck and cover. My little plecos get really scared around me and as i walk closer to the tank they flare at me and then run away after I get too close. Some of the fish don't care like the discus, they puff up their chests and swim up to the glass like royalty, the catfish and gobies, and stuff get scared. They are really skittish. Is their an easy way to form a bond with fish? Do you think trying hand feeding would work?
