Just noticed the water in my tank is 30 degrees celcius (86 degrees farenheit) would this explain as to why my fish could be at top gasping for air, everything else is OK
the hotter the water... the faster it loses oxygen...
so I would quickly lower the heater temp (I'm unfamiliar with any fish that requires 86F; if yours do, then dismiss the 'lower heater temp' comment) and add a bubble strip/stone.
Also as Wilder said... there are other details that may be playing a part in this and the more info you throw out there the more people will be able to help.
I got my tank yesterday and i accidently had the heater to high ) - when i went to bed the water was 26c 79f and had been for a hr or so but when i woke the water was all misty(it was clear the night before) and the temp i dunno what it was but the water was warm and above 86f(what is the max temp i can read) It wasnt like boiling, just warm.. i turned the heater off at 1pm, its now 11pm and the water has only just come down to 86f. The water is slightly clearer..im leaving the heater off to tomorrow and then going to turn it on again at a lower temp..
No Y2J, don't worry about it. As long as there are no fish, you can't do any serious harm by raising the temp a little too high.
kstacey, how did you end up with such a high temp? Most fish require around 76 deg F . Discus need higher temps but you didn't mention having any. Is the tank newly set up? Answer Wilder's question. Did you cycle the tank before adding fish?
Not too sure how the temp got that high as it was set to 23degress celsius (73.4 degress farenheit) i've turned it down and turned up the air bubbles this seems to have worked as all the fish have come back down. I'm assuming it got warm as the tank is next to the window (which has curtains up) which is joined to the conservatory, it gets very warm in there during the day. Thanks for the suggestions.
