Pet Forum / Aquaria / General / July 2006Too Hot For Tropicals
After loosing a few fish in the summer of 2003 I've now got a reliable routine for keeping the fish cool. I leave the tank flaps up and let a fan play softly over the water. Simple, but yesterday my tanks didn't go above 79 degrees F all day. Despite being called tropicals they really suffer in the extreme heat, so you need some way of keeping them comfortable. I change about 25-30% of the tank water weekly, so loss from evaporation isn't a problem.

My tank has been over 80degreesF/27degreesC a few times over the past couple of days and all I have done is change about 30% of the water with cold water from the tap(treated of course). My fish have been a bit on the quiet side and 1 particular guppy has taking to hiding in one of my plants as if she were giving birth/playing dead!?! I have a couple of airstones as I know warmer water doesn't hold O2 as good as cold. I'm up in Edinburgh so not nearly as hot as it is down South. If this heat wave carries on, is there anything else I could do to keep my fish(community tank) happy? Signature!Speedy Gonzales!

I'm not sure how wise it is, but I have tried it in extreme weather and it does get the temperature down. That is creating your own fish tank icebergs :-) Fill up a tupperware container with tank water, freeze it, and then put the resulting iceberg in the tank. I have heard the very cold water close to the berg isn't good for the fish, but none of mine seemed ill after I did it. A brick size berg will bring the temperature down by 5% or so. SignatureEdward Cowling London UK My fish look fine, though the temperature is high. However, there were an awfully large number of dead fish, mainly sticklebacks, in the river Soar today. > I'm not sure how wise it is, but I have tried it in extreme weather and it > does get the temperature down.

Since upgrading to marine, I am having some terrible trouble at the moment keeping temperatures low for my corals. The problem with the 2 litre lemonade bottle is that it floats on the surface under the metal halide lighting and melts too quickly, also blocks out the light. I have tried smaller 500ml containers in the return chamber of my sump, but they thaw too quickly, in less than 10 minutes at 80F. I have just bought a fan which I am going to try and locate over the top of the tank (mine is open topped by the way).

Ok I loose a good 3-4 gallons out of the tank in a week, but I do a weekly partial change anyway. Even today my tank water never got above 82, even though the room reached close to 90 at one stage.

Given what I've read in this group over the last few days, I've been gently washing my filter media every day to keep water circulation high, and I've left the top partially open today to encourage evaporation. I don't think any of my fish are jumpers. Or at least hope not. I keep things just about stable by leaving the lids open (no jumping fish!) and replacing the evaporated water with chilled (not iced) tap water every few days. That said, most of my fish are tetras and cats, which are generally very tolerant of varying conditions. >I keep things just about stable by leaving the lids open (no jumping >fish!) and replacing the evaporated water with chilled (not iced) tap >water every few days.

I've a few White Clouds who are borderline for a community tank anyway as they prefer cooler water. But yesterday the tank never went above 82-83, so I'm happy I can keep them comfortable.

In the hot weather the tank temperature has reached 28 degrees. I've been watching the tank carefully... no ill effects. However, the tank is well planted and isn't especially well populated. I've said to myself, I'll take action if the fish start behaving strangely or the temperature reaches 28 degrees. Fortunately, with 200 litres it's relatively stable in the temperature stakes...
