Well the temp is 27-28 because of the discus that was in there before. They've been in there since yesterday and they're not showing any stress, no damaged scales. They're wild caught. They were in a 10g but they kept fighting so I moved them and now they're swimming together and following the shrimp around. Some people assume that because they're from ponds and rivers, they're cold water but if it's sunny down here then the ponds are heated to about 22-24 anyway.
