I should have used shrimp to cycle but I learned that after my lfs told me to use dammsels
You and me both.
well the WQ looks ok (considering the cycle), you can expect the ammonia to keep getting higher though. I'd say when it starts getting over .5 you should do small water changes to keep from killing your damsels. It's not too late to take them back to the LFS
. A lot of folks end up taking them back eventually anyway as they can end up quite agressive. take em back and drop in a shrimp, you've already got some ammonia in your tank so that will keep the cycle going while the shrimp warms up
The rising ammonia is certainly stressing your damsels and their surface breathing could be a symptom brought on by something else thats affecting them due to the stress...
