Hey everyone new peacock bass keeper. I have 2 kelberi bass 4.5-6.5 and 2 xingu bass both around 6 in a 210gal. Everything was going well for a while but then noticed one of my xingu pretty much charges all 3 bass n puts his mouth on them but isn't bitting but it's non-stop for a day and then everything is normal and then a few days later it comes back. I'm assuming he's showing his dominance but no one is fighting back so not sure why he will keep doing it over and over again. Would a dither fish like tin foil barbs, geophagus or silver dollars help with this aggression or do I need to add more bass?
