Panda cories & Columbian tetras: temperature

[dcom]

My new 37 gallon tank will soon be ready, finally, for stocking. The two fish I hoped to build around were panda cories and Columbian tetras.

However, after searching widely through the internet, the general concensus seems to be that pandas are happier in cooler temperatures (around 68-75), and the Columbian tetras prefer the higher end of the range (around 75-80).

From your experience are these ranges right for these fish? If so, do you think I should work to the middle, around 75 degrees, which would put both more or less at the limits of their comfort zone? Or abandon this pairing?

If I had to choose only one and work within its range, I would probably go with the pandas because they are a nice size cory and available locally. What would you suggest for a cooler tropical tank, and held at what temperature? (During 2-3 summer months it would probably have to remain at around 76-77). This tank is 12x30", but 22" deep, so swimming levels will be important for a balanced appearance.

Most fish are able to adapt to different water prams including temps. As long as you acclumate them slowly they should be fine. I would say to go for a range of about 75-76d F. The cories will be fine with a temp of this and most other tropical fish will like this temp. I have some pepper cories and at times the temp has hit 83d F and they were fine. As long as it isn't a constant then you will be fine. You can go ahead and mix the above fish without any worries.

dont let it get more than 78 degrees without good oxygen levels or the cory might stress...

If they are like my Cardinals that can tolerate higher temps the best medium for me has been 75-76

My cardinals are happy and so is the cory.
When I first added the cory (there is only one atm but im getting 2 more soon) he would stress when the tank got really hot so I lowered it to 26c degrees happily...

no problems so far
