This is my kids(son/daughter) tank. They both wanted a little something in the tank. So I had to with the pink gravel for the girl and sponge bob for the boy. They have 2 goldfish, 2 frogs 1 kissing gourami, 2 neon tetras, 4 white clouds, 1 betta, and 1 bala shark. They both picked out different fish, so it was kind of interesting doing it the way they wanted it but it worked out.
