Cardinal Strugglling

[marknash]

after looking at him a bit closer... he's got tears everywhere. very mangeled looking. we do have another cardinal and watch to make sure there is no fighting going on.. they just kind of hang out together, and seem to get along as well when the lights are off. Do you think this sounds like hes being picked on? what else could cause all the rips in his fins? hes sick anyways and i dont know what to do for him.
