Hi, I have a setup with my baby south americans in it, i have an escondido carpintis, a red belly pacu, a bay snook, a jack dempsey, and a peacock bass. They're all 1 to 2 inches long. I got a new heater for them and i need help choosing a temp. I am mainly focussed on my carpintis's need. I want to go warmer to boost their metabolisms. I have it at 76 degrees farenheit but i want to go 80. Is 80 good?
