Bushy nose male acting wierd

I came home to my Male up in the top corner by the heater today. I noticed a small open wound on his head yesterday it seems to be better today his dorsal fin also has a tear in it vertically. All water parameters are good ammo 0 nitrite 0 nitrate 20 pH 6.6 to 6.8 water changes performed twice a week 25% changed the female seemed a little aggresive towards him so i wonder if its something she did to him they laid eggs a month ago and i sinced moved the babies. they almost seemed as if they were going to breed again but since i noticed him in the corner shes been mean. I moved him to a hospital tank with a pair of cribs and he seems to be doing about the same, and the kribs leave him alone. So i"m stuck on what to do Help!!!!

also no signs of ich or any other illness on the body

btm, we may need to have more details or a photo or two to help you more...
sorry to hear of the injury to your pleco..
