i have a tiny 30 gallon with 3 species of Ps. theyre doing good so far, they ate one of the smaller reds, but that was only when i introduced them. there are 2 natts (1"), 2 gold spilos (3-4"), and 1 spilo cf (4.5") with some breeding guppies. the spilos are the oldest inhabitants about 7 months, the reds i got about a month ago, and the CF is about a week in the tank. would u guys think i need to seperate them in the near future?
