sigh... just as i get over my mousey dramas, i get this with my fish. 
so,... one of my bettas has been slightly off lately. just slightly. people that dont know him would think hes normal, but he hasnt been acting as active as before, and is it just me, or is it when hes resting he seems to clamp his fins a bit.. maybe im paranoid... 0_0 but now, theres a small little cloudy area on his eye. it looks like a small-scale cataract, the eyes arent bulged, and theres no raised surface or ring around the eye like popeye. i have a (crappy) pic of him, its the right eye, and no its not the reflection, that areas always there..
oh and also, hes been flaring a lot lately, so now hes got a gill cover that doesnt cover all the way. the insides arent inflamed or red, but its like maybe hes... overdone/worked it? his color hasnt faded or anything, and eats like a pig. tips or help appreciated! D:
