Did you regret buying any particular fish?

My dad regretted purchasing large Angel fish because they started attacking the other fish in the tank! I always thought angel fish were pretty, but I had no idea they were so aggressive. Eventually he chose to sell those fish and the tank was peaceful again, albeit with less fish in it since some got killed.

I somewhat regret getting Fancy Guppies as they will not stop breeding and I can't seem to find anyone who wants to take them. I was told I had all males and I was given a female and I didn't notice until it was too late.

Moreover they produce excess amount of slime production and are very easily susceptible to diseases. So I totally regret buying angelfish.

I love Arowana and I bought a very small fish, it quickly grew. One day when I wasn't home, it broke the tank and died, felt very bad. Should have gone with a thicker glass or acrylic tank. Felt very sad and disappointed.

I regretted buying some shrimp that bred out of control.

Over the years as a kid and as an adult myself we have had many fish. I remember when I was younger my parents used to have a huge sized standing tank that we had quite a lot of fish in and I always remember we had Goldfish, Minnows and there was another fish that we had that would stick to the side of the tank and eat algae, but the name escapes me of what the fish was. We also had a pond outside with large goldfish that used to belong to my grandma for years prior to us getting the pond and the fish and they lasted so long.

For me I would have to say it wasn't so much a regret buying the fish, but it was where I bought them from that I regret and that was Goldfish I bought in 2019. I did everything that I should do to ensure that the water was fine for the goldfish that we had bought but we still lost them a few weeks later. We believe they had problems beforehand that we were not aware of or the owner of the shop we bought them from didn't fully tell us all that he needed to. We ultimately decided to buy two more, did the same things to ensure the water was how it should be for them and again, they died a few weeks later. I have been put off buying any fish anymore now until I find somewhere else that sells them that would be more professional than the person, I bought them from before.

I regret placing guppy and betta fish in the same tank. But thankfully before anything could happen I gave my bettas away.

I made a mistake of having male Siamese fighting fish in my tank with other fishes and it attacked all other fishes in no time.
