It amazing how it starts. Last year we got the kids a fishtank for christmas. They always adored the fish section at the pet store. So we started with a little 10g tank with platys and swordtails. The kids lost interest in the fish of course, and don't go near the tanks unless I am doing something with them. Since that initial 10g, we now have 2 10g betta tanks, a 40g community, a 55g malawi tank, and a 75g Severum/Jewel tank lol
So much for getting the fish for the kiddies lol
