Best fish/fish tank ideas for an almost 17 month old. Would prefer a smaller tank but not one she…

I got a beta fish for my daughter around that age and put it on her dresser .but had it pushed back so she could still see it && would let her help with feedings .@tel5355,

We got a 10 gallon and did guppies and platties. We turn the light on at night as a night light for him. He loves it. He pulls a chair over to watch them and he wants to feed them. He says fish all day long lol
