Hey, I just bought a Tiger Oscar a week or so ago and everything was going fine until I cleaned the tank for the first time. it wasn't anything big or anything all I did was take some water out and put some fresh water in and scrubbed the tank a little. Now for the past few days it seems like my Oscar is almost afraid of me. Whenever I walk next to the tank it lays flat on the the bottom of the tank like it is going to die or something, but I watch it from far away and it will act it is perfectly healthy and swim around like nothig is the matter. I don't know if it is really afraid of me and just needs time to adjust or if something is really the matter. Has anything like this happened to any of your guys's fish before?
