Most people seem to get sucked into this hobby when they are kids. My parents had a tank when I was a kid (maybe 5 or 6). I think it was a 29 gallon with some guppies. It was fun and I enjoyed it from afar, but I never got "into" it when I was that young. Eventually the inhabitants died off and fish-keeping faded into the annals of my childhood memories.
My next encouter with aquaria was when I was 20. The standard story of "I won a feeder goldfish at a carnival" story applies here. Got my new friend a cheapy 2 gallon hex tank with UG filter setup from Petco. After the feeder died due to an uncycled tank, I went to Congressional and got a Dwarf Gourami. He died pretty quickly thereafer as well. At that point, I did some Googling and found out about the nitrogen cycle and learned about how small tanks are often more difficult to keep stable. It was then that I was hooked, and determined to keep a fish alive for more than a week. I went out a got a HUGE 10 gallon tank with it's own dedicated hang on back filter. I even got a heater for it, and an API master test kit! At that point I felt like I was surely set up to succeed.
I began the interminable wait of a fishless cycle. It was definitely tough to wait to not get any fish. Looking at the big empty tank on my dorm room desk, while at the same time all of my dorm buddies asking why I had a fish tank with no fish in it, seriously tested my willpower. But I stood strong. I tried to tell them about the nitrogen cycle and why adding fish now would be certain death, but they got bored of the conversation and switched the topic quickly to something else like the new hot transfer chick down the hall.
Eventually, my test kit showed 0, 0, 5. Could it be that it was ready?! I trusted the process, and went back to Congressional to get another Dwarf Gourami. Much to my delight, he survived past 1 week! Everything was going great until about the 1-month mark, when his belly ballooned up. I panicked, and again back to google! AH, bloat. Off to Giant I went to buy a bag of frozen peas to stuff into my tiny dorm fridge's freezer slot. I spot fed that little gourami frozen peas 4-5 times a day, between classes. And then he died. I was distraught.
Google told me that this was a common ailment for dwarf gouramis, and that if I were to try again it would likely result in a similar fate for the poor fish. At that point, I decided to try other species...and live plants! DIY CO2 reactors, and Eco-Complete, and light upgrades abounded. The rest was just a whirlwind of upgrades and stock changes. At one point I was breeding peacock gudgeons, but after graduating and moving into our house with my then fiance, the fry all died off and the parents did as well.
Fast forward to just about a month ago, when I set up my first monster tank, a standard 6 foot long 125g, to house my baby Oscar who I knew would outgrow my 40g-long river tank when I bought him. With only the 125g running, I'm not as committed as some on here who have entire rooms in their homes dedicated to racks upon racks of fish tanks, but I have always enjoyed my time in the hobby even though I've only ever really gotten ankle deep into it.
