I can't figure this out

I am creating an ArrayList of Fish objects. I basically am building a flocking demo using XNA studio. I have a class called FishManager, and one called Fish. I want to add another class called FishGroup, but for now I have to figure out this problem. I am randomly creating the Fish's location and other properties including direction. I walk through the debugger and each fish has different values for everything except the ones I set. After I run the program when I go to draw the fish they all end up with the same values, it really doesn't make sense. I walk through a couple times with the debugger and each time more fish become alike. If someone can see what I'm doing wrong I would really appreciate it. I made sure that the array the constructor is only getting called once, but I am just lost to why I am having this problem.

[code]

namespace Flocking.Fish

{

classFishManager

privateTexture2D[] east_image =null;

privateTexture2D currentTexture =null;

privateArrayList group1 =null;

staticbool FishLoaded =false;

//This class should only be created once

public FishManager(GraphicsDevice device)

{

FishLoaded = LoadFish(device);

//Create Fish

group1 =newArrayList();

Fish tempFish;

for (int i = 0; i < 10; i++)

{

group1.Add(newFish());

}

}

privatebool LoadFish(GraphicsDevice device)

{

east_image =newTexture2D;

east_image[0]=Texture2D.FromFile(device,"Sprites/ball fish e0000.bmp");

east_image[1] =Texture2D.FromFile(device,"Sprites/ball fish e0001.bmp");

east_image[2] =Texture2D.FromFile(device,"Sprites/ball fish e0002.bmp");

east_image[3] =Texture2D.FromFile(device,"Sprites/ball fish e0003.bmp");

east_image[4] =Texture2D.FromFile(device,"Sprites/ball fish e0004.bmp");

east_image[5] =Texture2D.FromFile(device,"Sprites/ball fish e0005.bmp");

east_image =Texture2D.FromFile(device,"Sprites/ball fish e0006.bmp");

east_image[7] =Texture2D.FromFile(device,"Sprites/ball fish e0007.bmp");

returntrue;

}

//This function draws the east images without rotation

publicvoid DrawFish(refSpriteBatch sprite)

{

foreach (Fish ain group1)

{

int index = a.getFrame();

if(index <= 0 || index > 8)

index = 1;

tempX += 35;

tempY += 35;

Vector2 tempPosition = a.getPosition();

sprite.Draw(east_image[index], tempPosition,newRectangle(0, 0, 64, 64),Color.TransparentWhite, a.getRotation(),newVector2 (32, 32), 0.75f,SpriteEffects.None, 1.0f);

}

}

}

classFish

privateVector2 direction;

privatefloat speed;

privatefloat MaxSpeed = 25;

privatefloat DesiredSpeed = 10;

privatefloat senseRange = 100;

privatefloat seperationDistance = 20;

privatefloat currentRotation = 0.0f;

privateVector2 position;

privateint currentFrame = 1;

public Fish()

{

Random rand =newRandom();

int xValue = rand.Next(25);

int yValue = rand.Next(25);

direction =newVector2(xValue, yValue);

direction.Normalize();

determineRotation();

speed = rand.Next((int)MaxSpeed);

//Make sure fish spawn in the box from 200, 200 to 400, 400

int startX = rand.Next(200);

int startY = rand.Next(200);

position =newVector2(startX + 200, startY + 200);

}
