Normally my betta Mac is really happy and playful. I recently moved him from a 1 gallon tank with no filter or heater into a 5 gallon one with a heater and filter. I moved him into his 5 gallon one yesterday and didn't buy the filter until today. I'm assuming we just stressed him out way too much but I'm still a little worried. We had to fix a few things in the tank 2-3 times and he ended up flaring at me which never happens. The water was way waaay too cloudy because I never filtered the tank and let the water age for 24 hours before putting him in (I never knew, I'm new to this). So right now he's in his old 1 gallon tank for the night while his new water filters and he's not moving at all. He's floating at the top and his little fins aren't even moving. I got nervous that he died or something so I softly tapped the glass and he FLEW across the tank. Do you think he was just sleeping and I scared the **** out of him? Everything in my water is fine, I've been doing tons of research and have gotten the kits to test the water. Should I just leave him alone for the night and let him calm down? I'm new to this and I'm really attached to him so I'm getting worried lol.
