I have a male and female kribensis in my tank at the moment and the temp is set at 26ish degrees, I read in a site on the internet that they are ment to be in 25degrees temp. I have had the male acouple of weeks now in the 26ish temp and he's been fine as far as i know, (he doesnt say alot), he doesnt seem stressed. I got him a girlfriend today and put her in with him, they seem fine, but should i lower the temp? I have quite alot of offer fish in with them that prefer the water 25- 28degrees.
