Swapping things over from a 14g biocube that has two juvenile perulas and a yellow clown goby in it. I plan to get a prawn goby when one pops up at a lfs and then some type of dwarf angel would be nice. Something colorful if possible. Is there a specific dwarf angel that would get along with my clowns and gobies as well as be ok with a 40g tank? 24x24x16
