they are self-reproducing
Cells are of a small size because of consideration of the proportional relationship between surface area and volume. The size of cells also becomes a benefit when considering the rate at which cells die and are being replaced.
Why can't certain cells,like bacteria,get to be the size of a small fish
No. They are all similar in size. However, larger animals do have more cells. For example, there is a big brick house and a small brick house. The bricks are all the same size but, the big brick house has more bricks.
DNA is found in the nucleus of the cell, and when the cell is small, the information stored in that DNA is able to meet all of the cells needs. But as a cell increases in size, it usually does not make extra copies of DNA. Just think about a small town library with a few thousand books. If the town gets larger, there will be more and more people borrowing books, just like in a cell.
It is advantageous for cells to be small because they are able to get more nourishment. Their size makes them more efficient at diffusion.
No, all multicellular organisms have the same size cells.
All living things are made up of cells. Because they are small in size does not mean that their cell size is small. Generally cells are the same size between organisms.

No they do not. They all have the same size of cells.
Penis size is in no way correlated to brain power.

We can not give you an answer as you do not give a choice. However, cells stay small because they are the right size to function properly. Perhaps you can select an answer from that.
The surface area-to-volume ratio of the cell.
surface tension of plasma membrane
The cells are too small for scientists to see with the naked eye. For some perspective on how small cells are, the dot above the letter 'i' is about the size of fifty cells. Scientists could not see regular cells with the eye alone.
