40 is a little low... I wouldn't let the water drop below 60 on average, any more below that and their metabolism slows way down and they may now eat. Of the water is 40 in your basement you will need an adjustable heater to bring it up to at least 65. :)
And my babies haven't even hatched, so no worries. Lol
Do you think 40 degrees will be ok? I read on another site that the water should not go below 60 so I wasn't sure. I can't believe they go in the fridge!!!!!!!!!!!!!!!!!!!! I will definitely consider one of your babies but don't hold anything yet:)!
Another question: What is the coldest temp they can be kept at? I was thinking about putting them in my basement(don't worry, we go down there all the time and it is finished and cozy so I will not forget about them) because no other part of my house is ever below 70 degrees (except the winter) so the basement is my only choice. Another thing is: you they require a certain about of light? My basement is dark and only lit for about 1-2 hours a day (which is the time that we play down there) so the tank won't be getting a whole lot of light.
