Yesterday morning I noticed Ombré my crowntail had white dots in him, was hidding, rubbing up against things. I got ich med and got to of the stressors what I think caused it. (On Wed I got 3 new glofish. He was fine with the 2 I already had.) I know I need to raise the temp if the water, but my heater doesn't adjust. It's the tetra ht10. It's preset to 78, but currently the water is at 75!! I live in a basement so it's naturally cooler. I turned on a hot water humidifier and closed the door to my room to see if that would help warm things up. I currently don't have money to go but a new adjustable heater. Is there anything else I can do to adjust the temp? Ombré looks so miserable!!! He usually is so lively and loves to interact with me. :( I want my happy betta back!!
