bullying between catfish

[tracey]

it it possible that two featherfin catfish of a medium size can bully a fully grown hoplo catfish,to the point that the hoplo becomes ill with the disease called saddle back columnaris,it is also referred as cottonwool disease.the hoplo is really timid were as the two featherfin are very territorial.also are they the kind to attack a baby betta.thanks advice would be really appriciated.

Columnaris is a bacterial infection, and Syno's do have teeth, so I'd say it's possible that the Hoplo could develop a secondary infection if attacked by other fish. Stress also lowers the immune system, making infections easier to become established if the fish is injured. It would be best to quarantine the Hoplo, and treat w/antibiotics, then find it a new home.
