Goldfish? lessee- theres the 50 gallon tank with the 50 baby koi, the 50 gallon with the 25 shubukin and about the same number of red and white comets; the 30 gallon with the mixed 2 year old "babies" from the pond, the 30 gallon tank with the dozen or so "fall babies" from the pond - plus a couple leftover from the spring, and the 12 x 12 x 2 tank in the next room with 100 + babies from this fall.
