I know, I LOVE all animals! Ever since I was born, I have been an extreme animal lover! Right now I have 8 fish, 1 snail, 6 chickens, 1 duck, 1 hamster (I'm getting another soon), and 2 dogs. I wish I could have a horse...
Here is a pic of the size of the ball next to the tank. It wouldn't add much, would it? I don't think I'll put it in, anyways. It keeps leaking 'dust'. The pic makes the tank look small... (BTW, it's very hard to take a pic with a front-facing camera on a tablet with one hand!)
Anyways, I have come up with a plan for breeding the fish. I will wait until the babies are born, then sell all except either a male and female adult, or a male and female of the babies. Then, I can keep breeding with only 2 fish, maybe 3 if I keep 2 females. This way, I can keep the numbers in my tank down. Does that make sense to you?
Sorry for rambling...
