This is a bad one...
My first fish tank.
I found this 55gal I found on the side of the road with 1 pannel broken out. Being the sort of guy who loves to try to fix anything broken I see, I took it home, cut a new chunk of glass out of an old window, white ACRYLIC caulked it in, epoxyed in this section of roofing gutter to make a new center brace, and smuggled it into my door room which had a strict no pets, no fish policy. So, I sucker some buddies into makeing about 100 trips to the bathroom sink with 2L bottles, paper milk jugs etc to fill the tank. Once the tank was full, I headed straight to the pet store and asked the lady for the biggest baddest filter she had. She set me up with a fluval 403, and I still belive its the sole reason this tank worked at all.
So, I got some buddies to chip in, and I asked the lady what the most agressive fish she sold was, she set us up with 5 cichlids, and i bought a 3 dozen feeder fish at the same time to go with them (remember, i had never even heard of bio-cycles). So, we rush back, add everything to the tank, then worry about setting up the filter. It went together pretty easy, and I positioned the outlet on the side so the whole tank appeared quite similar to a giant whirl pool.
I had never even heard of water changes, and keep in mind, this tank was just bare, absoultely nothing but fish swirling in the tank. I had thought that substrate/decorations were only for looks...
So, by the end of the year, I had about 10 cichlids, 3 medium oscars, 5 beta (yes, all males) and assorted other things like eels, knifes etc.
This tank had only had top-offs its whole life, and was only fed live feeders, table scraps, and mt-dew. No heater, no lights, kept in the bottom area of a dorm dresser, no hideing places, and relentless constant current. Amazingly, it never actually never lost a fish for any reason other than fish on fish violance (I kept them a little hungry).
Anyways, so, at the end of the year, I fit all my fish into a milk jug with the top cut-off, and a few cut-up mt.dew bottles and take them back to the fish store. I opened the filter up for the first time that day before packing it up, and I discovered why I had thought i remembered the tank haveing a much stronger swirling effect when it was newer...
Poor little fish, I cant even imagine what the nitrates or water hardness was like in that tank.
I thought this confession of fish sins thread would be the only decent place possible to share this story...
