I have 3 feather dusters in my tank. They have been in the family 6 months now and have been doing really really well. None of them have lost any feathers or jumped out of their tubes...but....
I have notice that they won't go back into the tube when startled. I found one on the bottom the tank. I picked it up and it didn't even move. Now there is brown globs around the openings? It doesn't look like the normal waste? Are they sick?
What should I do?
Nothing has changed in the tank in 4 months. I do water changes often. Everything else is doing great.
