Looks like you have some pearlscale angels and some Black marbled ones from the pictures. I love Anglefish. They are so graceful looking when swimming around.
I just took down my tanks due to arthritis problems--( I had the Koi angels). 22 tanks was to much work--so now I just quilt
I do have my small pond next to my flowerbed though- now I just watch the goldfish & Koi swim around.
