Long term effects of tank being too hot?

[Tiggs]

I thought my tank temp (32) was due to the summer but it seems its more to do with the extra light and VERY close fitting lid - the temp above the water and below the lid gets VERY hot............so much so that my hatchet fish (surface fish) swims 6 inches down!

However, apart from my shrimp population dropping dead everyone else seems fine......so how important is it to drop that temp? the layout of the tank means the only way to that would be a chiller - theres simply no space for a fan or cover removal.

What are the problems with hot water? i assume there must be tropical places where water temp hits low 30s?

yes! there are places where in the water is a bit warmer.

Generally the common plants being talked about here are usually sensitive to extreme heat take a simple example , java moss i cant grow it no matter what i try because my tank temp is roughly 31-32 (thats why im working to cool it down) other plants like sags and my rotala rotundifolia, crypts and stargrass are doing fine, the inhabitans of my tank are cardinal tetras which i believe wont die because of the heat but become stressed, i had corydoras before but they gave up due to the summer heat...

so IMO its not really bad as long as the inhabitans of your tank can take the heat

hope this helps

Hi Tiggs,

I've got this problem with my 5 gallon. I added a condensation tray and now the temperature is 28 degrees without a heater.

I'm sure I've seen a post somewhere where someone put fans inside their hood. I think its in the DIY section. I assume this was to cool down the heat given off by lights, but not sure.

hi tiggs.

as well as the problems mentioned above if the temp gets too high you will have oxygen problems. i'm not sure of the exact temp where it is considered an issue but as temp rises disolved o2 content drops.

i think 31/32 is around the danger area as at this temp all my fish turn into surface feeders!!

my fish are fine unless i dont use an airstone at night....if i do that they are in trouble - as it is, i run an airline to generate surface movement from lights out till 1 hr before lights on - fish show no signs of O2 probs.............in fact, the only thing they do is that the cardinals hug the bottom in the eve where the temp is less after a full days lights.
