Ok question!! I have a 40 tall with one adult angel, 5 harlequin rasbora, and a bristlenose pleco. This tank will be a Blackwater tank soon so it will be very dark in color. I am looking for a fish to add that will enhance the tea like water color. I like the way the rasboras look because they have that brown tan color with black and my angel is very natural looking, with browns and blacks also. I'm wanting to keep the natural look but these fish don't have to be black and brown. I'm looking for something that stays somewhat small, can be in a group of 2 or 3, will look good and natural in blackwater, and will get along with my fish. Any ideas??? Thanks everyone!! And also everything is welcome, so bring on the suggestions!!
