I am having to tank a couple tanks down because of to much humidity casing mold so. i am selling my cichlids and putting something else in my 55 gallon. soo.. could anyone help me ID these 2. The blues aren't very colorful right now. And the silver/ black on is it female or male? i was thinking female but the last few months it seems more like a male. thanks! EDIT: I know they yellows are labs thanks though! Just need the blue and silver with black id.
