When my mom was young, she collected fancy gold fish. She came home from school the day after checking her equipment (routine) to find all of her expensive goldies bright red and essentially, turned inside out! Turns out she'd accidentally turned the heater up to maximum heat, and fried the poor things. I remember when she told me that story. It was on the way to buy our first tank...

In the 90s we had a saltwater tank,once a month we took everything out and placed it in 10 percent bleach solution,so stupid now as we realize it was pointless and less tan beneficial.
 
OH BOY. WHERE DO I START?

When I was but a wee lad, I let my dad put the 15 gallon goldfish and pleco tank onto the balcony. During the Canadian winter. Because he told me they were coldwater fish.
Conclusion: Biggest ice cube I've ever made.

I bought a dozen goldfish as feeders for a Chinese Pond Turtle that later died because it wouldn't eat. These feeders ended up in a 20g. That was heated. I fed them on a diet of only freeze dried bloodworms.
Conclusion: They all ended up with dropsy.

2 years later, I kept a pair of Kribensis in that 20g. I thought I could introduce a 2nd pair without problems.
Conclusion: Nope.

Introduced a big female betta to a dwarf rasbora tank because I figured if my large angelfish couldn't eat them (I tested), the betta surely couldn't either.
Conclusion: Over the course of 2 nights, it ate all the rasbora and proceeded to die on me immediately after as a big FU.

Treated a betta with fungus and fin rot. With sea salt. At a marine level dosage.
Conclusion: Wut do u theenk hapend?

On a separate note I've had two Chinese Pond Turtles escape the enclosure and jump off a 7 story balcony. I've also had a Russian Tortoise in an outside enclosure get a surprise visit from a family of black bears
 
I liked the first answer on this thread. Not getting a big enough tank is a good one. Another big regret of mine was killing so many fish that I love (fresh water puffers) out of ignorance. They are what moved me from just a goldfish guy to getting into fish in a big way. It's been many years since I first had a puffer, but they helped me make the transition to cichlids etc. The problem was partly mine, but also a lack of clear information online (this was 2005/06) about how to keep puffers. At first I put them in fresh water and they died. They I put them in brackish water, but it wasn't marine salt it was aquarium salt and so again, more died.

Today I know how to keep puffers, but I'm gun shy because I lost a half dozen or so and it bugs me to this day. Another regret was keeping German Blue Rams in water that was too cool. I had them in a 78 degree tank because that's what so many websites said a year ago. Corey from Aquarium co-op seems to have made people come to their senses about how GBRs need warm water (82-86). Even my LFS now specifies on all of their tanks that GBR's need 84 degrees or higher. I lost a beautiful big guy just to sheer ignorance. I almost cried when I had to fish him out of the tank the day he died. Losing fish sucks ass.
