I have 4 angels in my 20 gal tank. I also have 3 zebra danios, a rainbow shark and a pictus cat. They have all gotten along fairly well until lately. I think the danios are bothering the angels because they tend to hang out closer to the bottom of the tank rather than higher. I decided to eventually transfer the danios to my new tank when I set it up hopefully this week. With that understanding I added a dwarf pleco to take care of the algae. I added him on Saturday and the angels have been acting strange since. When I walk up to the tank instead of coming to the top in a group, they are getting all skittish and a couple of them are actually running into the walls and the gravel, one seems to be breathing rapidly and is stressed. They also splash at the top like they are trying to get away. Are they ok or sick? What can I do?
Thanks for the help.
