My 09 female just hit 300 grams. Put on 60 grams in 3 months, big improvement. Went to 2 rat pups, and now on small rats. Guess I'm going to have to upgrade the 10 gallon tank this summer (probably at the Daytona show). Still undecided on a tub or a tank, or maybe one of those plastic gigs with a plexiglass slider, I'm open to suggestions on brands if anyone has used one.
