I have two sens in a 75 gallon with an african knifefish, kribensis, and a recently bought african butterfly fish
I just saw one of my sens (the slightly more aggressive one) go up to the butterfly fish, float next to it for a few seconds, and then bite its tail. which made the butterfly fish scurry into the plants.
so is the sen just nipping fins? sizing him up to see if he can eat it (he can't)? just curious to "what the heck is that floating brown thing up there"?
