I have had about 15 kuhli loaches for about a year with no problems or illnesses. Today, I noticed that many of my loaches were out of hiding, some up by the heater, some just on the floor of the tank. They don't seem agitated or ill but it's not normal for my fish to just be out in the open like this, especially during the day.
The only change I have made recently is adding real plants and getting rid of the fakes, but that was about a month ago and I would think that would be beneficial to them.
I tried looking through the archives and reading all of the health information and didn't find anything regarding this.
If anyone has any suggestions, I would be eternally grateful. I am so scared that something is wrong with my little friends.
