heh it's true, i had a swordtail fry. about less than a cm long, gave em to my friend and he put it in with his full grown angels. for months the swordtail was chasing the angels like crazy scaring the.. sinking pellets out of em. little fin nipping creature.well, the angels got big, but he didnt really grow, amd they got their revenge... with murder.angels have missing and torn fins. wouldnt be too suprised to see em knocked dead from fin rot/injuries/fungus soon
