I am upgrading my tank this week to a 240L and want a group of shoaling fish. i am thinking of tetras and have been lured in by flame, rummy nose, lemon, purple emporer and penguin.... dont know why just have!!!! they are to go in with 3 polka dot loaches, 9 corys, 1 dwarf gourami, 3 platys. i want to also add a group of about 6 rainbows eventually to finish the tank off. can anyone give me ideas on peacefull, pretty tetras? are the ones i like ok? i am after a good shoaling group of about 9/10 depending on max size. i do like the look of neons too but fancied something a bit different, although the black neons look kinda cool....... cant make my mind up, please help......
