I am not sure if I am putting this in the right spot, but this is my first time on this forum. I have a 26 gal tank and a blue damsel in distress. I came home and she is laying at the bottom of the tank, she is still alive but is having a hard time breathing. she will swim if I try to net her. My clown died 2 weeks ago and the yellow tang died about 3 weeks ago. The levels in the tank are reading normal. I just bought a skimmer for the tank last night(seaclone 100), I don't think this stressed her out but I guess it may have. I also have a chocolate chip star fish, a peppermint shrimp, a snail, 3 aneomes and a hermit crab. They are all doing fine, can anyone help me figure out what is wrong with my fish? Please and thank you!

P.S if I entered this in the wrong spot could someone let me know the procedure.
