Just got some new platies today - 5 . 3 females and 2 males. I,ve placed the bag in the tank to even out the temperature. my tetras - one redeye and two others ( silver body with red fins and a blue strek up ther back - any1 know what name??) have been swimming up and nipping the bag. i,ve fed them so theyll be less agressive. do you think theyre curious or death hungry??
