So I am in the process of setting up a pico reef and plan to have an ornimental shrimp or two be my first livestock. The problem I have is the tank is in a sunroom with no air conditioner during the summer. Water temp averages 85 degrees but fluctuates from night to day. I am currently not running a heater and no light is on right now. I plan on running the lights when the sun goes down until it gets cooler outside. Question is how hot is too hot? At 85, am I going to wake up to a cooked shrimp?
