The first picture I believe were stiphodon elegans. Gorgeous discus. Do you know where they came from? The ones in attached photo are from a local breeder near me, still really young.
What all do you keep, I actually run a fish store in fort worth. I quite often get people from Dallas coming to my store.
Sounds like you need to find a fish friendly apt. then. I find it really relaxing to just sit back and watch.
I had a huge 800 gallon pond before I moved and taking care of it was lime having a zen garden. Always put me at ease.
