I am too affraid to add any livebearers (considering they breed to know end lol).. and i would hate for my babies to get stuck up in the filter like nemo ... I went to the store yesterday and bought four neons, they seem to be holding their own so far... the one white skirt tetra that i have seems to chase them once in a while, but they are good escapers... I think they just need to figure out their own territory, I also picked up a really neat colored pleco.... Today I wanted to buy a few more fish to add, so i picked up three white clouds (they are pink and red)... and two head tail light tetra i believe... they have not been added to the tank yet (they are sitting in the bag getting used to the water), I'll post pics later
