So I had a family member that wanted to get fish for their kids. Asked if I had any suggestions and or equipment. They didn’t want to invest a lot of money just in case the kids didn’t stay interested in the hobby. I gave them a twenty gallon long, stand, light, undergravel filter, air pump, HOB, gravel, heater, and food and some swordtails and cory catfish. After almost 2 years they called and asked …. Wait for it……. Here you go……if I wanted to buy everything. Hoping to get $50.00 for it all in a yard sale.
