Thanks for all the advice ! The temp in there is still 25, so I reckon they will be ok til the morning, will just have to go into work a little bit late...
I did have the heater slanted but obviously not far enough down to prevent what happened. I have a long tube thing for air bubbles and wondered if having the heater in this air bubble flow would affect the overall temperature...and also worried having it too close to the tubing might cause it to burn.. ?! Am I making any sense?
The lemon's have calmed down, in fact all the fish seem fine apart from one of the female guppies who has something sticking out of her mouth...that's been there since Friday... I tried to pull it away from her but she just went wiggly mad so I had to stop...it's like a thin blade of maybe plant root or something? I'm at a loss to know what to do about it actually..hoping it might work it's way out somehow...
well, fingers crossed they will all be warm enough over the next few hours....I got the fluval heater on recommendation as the temp is easier to control on them, they also have automatic switch off if it breaks so that the water doesn't boil up...like some of the horror stories I've read ..the previous heater was cheaper at £15 and had no cut off, only noticed there was a problem when OH noticed the temperature had rised to 30! Luckily it was spotted in time...
anyone have any heater recommendations?
