Hello I have been researching information on platys and I can't seem to find a specific water temperature for them. I know they are supposed to be tropical fish. But I can't find a temperature that anyone seems to agree on in my extensive research. I'm pretty sure my tank is room temperature but I don't have a definite number. I'm researching tank thermometers right now and would love suggestions. I'm also looking into heaters just incase I need to get one. Are platys ok in cold water? What warning signs should I look for if they aren't? Help please suggestions appreciated!
