New, but cycled tank. Plenty of plants and cover. 5 male guppies introduced last week. Readings zero, ph 7, temp 75 degrees.
Have been away for 2 nights and a day. Left one of those holiday sticks for fish- which they've been picking at. One now has a split in its tail and there seems to be quite a bit of bullying going on- he's chasing others, and one's chasing him, and another two are having a go at the rest. What's going on? Upset routine? Too many males?
