Not sure what type of cichlid, but he/she is a beautiful blue fish. I left for vacation this past saturday and came back tuesday and noticed him/her not wanting to eat. I also noticed it shaking while it's swimming. It's not all the time, but it would swim to a corner shake and then start swimming again. The other 4 "bond" together and swim in close proximity while this one is off to the side which is not normal.

nothing on its skin, and he doesnt seem to be eating.
