I'm going to stock it with mollies and platies, maybe even a couple of guppies.
I do have a question, though. What would be the ideal temperature for those three species? I have the temperature gauge on the heater set as low as it will go, 68. Right now the thermometer reads about 75 degrees, and it can get up to 78 in the afternoon, even warmer depending on the temperature outside and when I turn my air conditioner on. Is this too hot for these types of fish or will they be ok?
The fish you mentioned need hard alkaline water with pH between 7.5 and 8.0. The mollies and guppies would prefer warm temps of 78 to 82 degrees F while the platy's prefer cooler water with temps between 72 and 75 degrees F in my opinion.
