Lately my female normal has been acting rather odd, she's about 2 yrs old, 1500gr, and lately it seems she has an extreme hunger, I feel she would eat everyday If I would let her, she's quite active in her tank, always back and forth across it, she just shed about 2-3 weeks ago a d is now in shed again, she hasn't went #2 since she last shed, but passes everything else ok, what is going on here?
