my dad got like 60 fish that have really fancy tails and the look like guppies, my dad got it from my friend he said they breed like crazy, well is it normal for them to go to the top of the tank when i turn the lights off
yup. Fw fish pretty much do whatever they want and the guppies/mollies/swordtails were probly fed after lights out with their previous owner so they may be hungry
I keep my tanks more on the 75-80 degree range. I honestly dont think u have anything to worry about. If u r turning the ligths back on after turning them off they will get a little scared and stressed. its not bad with guppies. I have a spotted raphael and he will turn white if i turn the lights on when its late
