Tropical fish What happened to the fish? My fish, the water temperature is 28, and some fish often get smaller and swim unsteadily until they die, and there are no white hairs and white spots!

See if it's a feed problem! Peacocks are basically severely malnourished, especially the phenomenon that the mother fish will collapse after giving birth. Add some fresh bait, there should be many choices this season, such as water fleas and nematodes (be sure to deal with them! But this thing is super nutritious! ), bumper shrimp (you can buy some frozen ones if you don't want to hatch).
