Hi,
Hate is a strong word......
Try keeping them well fed and mix some veggie flakes or algae/spirulina for a change of pace...
They will always nip at plants..
Keep some hygro wisteria in the tank. They will FEAST on that and leave the blyxa alone more or less.
All species are very nice and better food/care/maintenance/etc will result in better coloration.
You just got them so they will not be showing their best colors yet...
Patience, they are nice fish. Fast, attractive, well schooled, hardy.
