After bugging me for a while, I decided to give in. This will be his first journey into any type of fish tank, and his main fish will be a puffer. I let him design the rock work and with a little help from me gluing it together, here is the start of his tank, just set up yesterday. I'm teaching him along the way why the tank has to sit and cycle and also how to mix the water and how the filtered water works, so he can learn not just what to do but why. So far he's learning a bit about the cycle and how to use the refractometer, and also what his favorite fish eats. Here is the first photo of his tank, a 40g breeder.
