my betta, "D", spends alot of time laying around or hiding. he doesn't appear to be scraping, but i could be wrong-he is my first. he will lay on the bottom of his tank, hding beneath the fake (silk) plant. you honestly can not see him unless you know where to look. he will also lay against the top of his rock OR you will find him laying across the rubber suction cup attachment to his thermometer. he just lays there. he eats well, and i have not noticed any evidence of parasitic infection. is he sick or just lazy?
