I have a coralife fixture in my 29 gallon open back canopy and the fixture gets HOT. Because of having the open back on the canopy though the heat is able to escape and have very little (if any) affect on the water temperature of my tank.

Thanks for those great suggestions BiscuitSlayer. There are only two very small holes in the plastic behind the filter, otherwise the canopy is pretty tight fitting, with the only way to increase additional circulation is to leave the feed flap open. I tried this but to no avail. I did leave the light canopy uncovered at night and did adjust room temperature down, and the temperature took a wild swing from 30 degrees celcius to 26 degrees celcius. I suspect when the canopy is replaced and the lights come back on, the temperature will again swing back up to 30 degress celcius. At least, now I will not have cooked otocat and shrimp, but fear that too many of these temperature swings, unless I figure out how to keep the temperature constant may well do the otocat and shrimp in.
