hey nice set up just ive had exsperince i use to have 120 gal tank before i moved onto fighter fish i had 2 angel fish and 6 neon tetras not a good mix i started having half eaten tetras once in awhile couldnt quite understand so one day i just was looking and witnessed angel fish bitting tetra and ate its head then asked around and angel fish are not to be but with fish smaller than them as much as they are adorable and so harmless looking they will eat things smaller than them if its easy target just something to take in consederation goodluck
