I have a pond which is relatively small 2mrts long x 1 mtr wide. I initially had only 2 adult goldfish but one died 2 months ago. However approximately 6 weeks ago I saw a few baby goldfish (about 4) but now I have somewhere in the region of 25 - 27 baby fish. Will they survive in a pond the size I have mentioned, the other surprising development it has 4 baby fish which are black from head to tail ? I never at any time had black fish but only the two adult fish I mentioned, puzzled
