Got home today and said hi to all the kids, noticed that Castle has some red spots around his gills, and even his ventral fins look a little more red to me; they were always magenta but look a little brighter now. It seems like it could be ammonia burns... But I have had him for four months now and never had an issue. Did a water change about 2 days ago, and now this. Haven't changed the water source or the water conditioner. What do you think?
