Mini Ponds
I recently answered a question on Yahoo fish about the efficacy of a highly planted 3 x 2 x 1 meter pond without filtration for guppies, crabs, shrimp,snails and a Slider turtle. While it might work, I suggested an air pump or powerhead for circulation. Too many plants can use up the oxygen at night, which is OK for livebearers, but maybe not for other fish. Also a pond that small should have a circulation at the bottom center, or the organic waste will collect there and eutrophy.
