I'm currently in my 3rd iteration of fish keeping.
In the late 90s when I was in middle school, my dad bought a 55 gallon we stocked it with Angels, Red tail shark, neon tetras, danios, common pleco, albino corys. We had to give it away when we moved from Utah to Texas in Dec 1999.
Then in 03-04 my dad was given a used 55 with a stand, light and an aquaclear filter. It just happened that a girl I liked in High School worked at a PetSmart. So to make an excuse to go talk to her I decided to start up the fish tank.
I murdered so many fish in that poor tank. I overstocked an un-cycled tank with, neon tetras, danios, a couple of angels, a couple of Bala sharks, a clown knife, common pleco. Sometime later after the tank had stabilized I was given a Tinfoil Barb. He proceeded to kill everything other than the pleco. After I met my wife and moved across Texas my dad kept that tank going for several more years.
After I bought my house in 07 my wife and I thought it would be cool for her 3 kids to have guppy tank. We got a Walmart 55 gallon tank and stand kit and filled it with mutt guppies and platys. We had a great time with the breeding and babies.
That tank is still set up and currently houses my Xenotoca Lyonsi Rio Tamazula. Now my grandkids come over and get the same excitement thier mother did with the same tank.
