I’ve noticed at the edges of the fins of some danio’s and neons have a white tint to them.
Is this something wrong? Currently one of my danios seems like it’s dying:
https://youtu.be/5wwFTFP9ocYCurrently having to do a fish-in cycle recently started. Water temp 22c.
74 litre tank 2.6ft long.
Ammonia = 0 (doing daily 25% water changes with Seachem Prime)
Nitrite = 0
Nitrate = 0
Any help/advice would be very much appreciated.
