So I recently did a major rescaping of my 180 gallon tank and added a driftwood stump to the tank. I spread out this process over the course of 4 days. Day 1 I removed all the plants that we were relocating and relocated several smaller pieces of driftwood. Day 2 I added the new driftwood stump. Day 3 nothing I let everything rest. Day 4 I added all the new plants and finished replanting some of the old ones. I have several young platinum angels in the tank that developed a red line under thier dorsal and pectoral fins and a reddish tinge to them after all of this. The only other fish that seems to be affected is a gold topped angel that is also showing a red line under his dorsal. Water parameters are all in line with only a slight elevation of ammonia (.25) which I am using prime in the tank atm to help mitigate. I am including a picture and am looking for advice. Is it just stress or something more serious? Thank you all in advance!!
