ok so when i satarted my large community tank, 300L, my first and tester fish were neon tetras and of course didn't school like i was hoping. now i only have 4 left and was wonder what i could replace them with. i have 9 haliquins and might get a few more so something different to them but still similar to the neons. not really keen on cardinals as they get bigger than i would like.
All suggestions welcome
