to answer bscaggs06 question, 6 work great in a ten gallon, in fact u may not even have enough food for all them unless u make it a point to specifically feed them. they clean up very well. as for the main thread, i know the neons will be fine cuz my sisters tank had both for awile. (however the shrimp did get killed by her fruit tetras. not even sure what a fruit tetra was before they painted it, i hate painted fish.)
