It's not really a fish but I think snails are over rated! I just don't see the point in them..

So true, why would you want mystery snails? They just breed like crazy.
You have one and next thing you know this happens.

I haven't kept any of them personally but I don't like glofish, any balloon form of anything, longfin morphs, and generally not albinos. I guess I prefer my fish to look more natural

Ewwww! I've had pest snails and thankfully I managed to catch them before things got too out of hand, but only because I had a small 5 gallon tank infestation. It's been about a month since my snail purge and I still find the odd one chilling in there

There are so many better alternatives to snails though, like shrimp! Shrimp are cute and funny imo and have next to no bioload (plus, even if they do breed, so many types of fish eat shrimp babies!)

Unless they’re out of the water and jumping, then they’re freaky...(one of the few things that freaks me out with animals)

Betta splendens, hands down. They’ve become so generic, like Tylenol.

Also, people always recommend them, but all I read every day is fin rot this, rot that, bloat, bubble eye, stuck on the filter intake, water flow is too much, torn fins, cooked alive, killed my Nemo, yada yada yada, bla bla bla.

Ok, so maybe not the worst fish, but one of the most overrated.

Wait, you don't like shrimp? I think they are so smol and full of personality!

I have wild caught ghost shrimp in my tank, I got them from a boat pond when my dad was preparing to go fishing, I got this one huge shrimp that bullies the fish in my tank.
 
I'm not much of a fan of livebearers, with the possible exception of Endlers. They breed constantly, are ridiculously common, aren't very interesting to watch in my opinion, and don't live long.
Also, Lionfish are terrible for the environment and incredibly invasive.

Eh, I find that to be a good thing. I made enough money selling them in the last 2 months to buy myself an Aquaclear 50 and a heater. You might want to see if you there's any interest in them locally if you already have some. Also, it's pretty easy to remove the egg clutches.

If you are in the south of UK I will happily take from you!!!

No no I LOVE shrimp, but when mishaps happen and they end up being outside of water... they start jumping in the air and it freaks me out. That’s what I don’t like lol

Ooooooo I was going to say disliking shrimp would be outrageous!! Yes they do look kinda weird as they flick themselves across the floor like a broken torpedo
 
Platys.Platys.Platys. 1)messy 2)breed like crazy 3)I've had a few that are just plain bullies no matter what I did
 
Some fish pet peeves of mine-
Aligator gar, Red tailed catfish, pacu, bala sharks, Iridescent Shark, arapaima, koi, knifefish, Common Pleco, bumblebee grouper, common goldfish.

Basically any fish that should not be sold to the general public unless they are proven to have the appropriate sized tank or pond (and some should never be sold in the first place)ead:
 
I'm having a love hate relationship with bettas right now. Lol. Don't get me wrong I like them and they are fun to watch but they are about impossible to stock around.
 
Common Pleco. I feel that folks are mislead about their taking care of algae and the size of tank they need to be in. Most folks don't really keep them in a large enough tank. Oh and I love my glo in the dark genetically altered Glow fish!
Too each his own!
 
Jelly bean parrots stupid tie dye. A long with LOTS of deformities. I talked to the manager. He said he will never buy them again as their gills don't work properly.20180811_153151.jpg

Glofish, I despise the way they look... I also don’t like jewel cichlids, the one I had was a little jerk.

I agree, I have 6 because my son got them for me and store made him buy six, and they just do nothing. No personality, blah. I'd rehome them if I knew somebody who would take them.

AND BLADDER SNAILS, EWWW, GROSS, HATE THEM, but my puffers love them, so they are good for something I guess.

Oh one other thing, ANGEL FISH. I have zero interest in them whatsoever.
 
In all of the Vietnamese fish store She I’ve been to for the past few days, they have dyed jellybean parrots.

Their bodies are extremely deformed and the dye they are injected with have almost no form of beauty and are just ugly.

Kinda have to agree I'm SO tired of answering fin rot questions and the people using bettafix and keeping bettas in a .5 container with no filter. I think it's because their great for beginners but company's also cash in on that selling "betta tanks" and "betta bowls" if company's backed away from that maybe we wouldn't have so much betta problems
 
I don't like platys and mollies. Not their looks, not their personalities. Which is weird to me since I love all the rest of the livebearers. Won't get fancy guppies again because the long tails annoy me--too easy to damage and makes it hard for them to swim.
Not a huge fan of incredibly shy fish--nocturnal species I get, but the ones who are just skittish? What's the point of trapping something in an aquarium if you're stressing it out just being around? And also not a fan of species where all the fish look exactly the same, like some tetras.

...but I love me some snails. My tanks are all full of ramshorn, bladder, and nerites, and I'm going to be getting Malaysian Trumpets, Assassins and Mystery Snails eventually. I'd love to find a place that had Rabbits at a reasonable price, and some of the huge pond snails. I also have a terrarium with land snails, and an outdoor pond just to breed more ramshorn and bladder. Something about the way they're just always on the move, scraping every scrap of sustenance off the surface of EVERYTHING...I just love that. Also my ramshorn in particular have a huge variety of body colors, shell patterns and differences in translucence, so they're all very individual. I have a lot of videos of my snails because I find them so funny, beautiful and fascinating. As someone above said, to each their own

Got a pair of land snails and they are fascinating.
 
In the home aquarium, I’m no fan of keeping “monster fish.” It’s cruel and inhumane imho.

why?

I think this mentality is to do with seeing the water:fish ratio being quite low, which I guess is a bad thing in most circumstances. Joey's tanks w/ monsters all have tons of swimming space
 
Ive never liked guppies theyre just plain ugly to me. I also can't stand deformed or dyed fish of any kind. But not the worst fish but the worse fish to have is a betta, you didnt rescue it, if money changed hands it was a purchase.
 
Ones that were pulled from their natural habitat to be put in aquariums (unless they were hurt and could be released back into the wild)

Hands down it's got to be GUPPIES, if there is such a thing as a pest fish it's guppies I detest them.
 
I'm no type a fan of any kind of cichlid. I know tons of people love them but I'll never have any just because the ones I've seen are aggressive and just don't look that appealing to me.
 
I might upset a few people by saying I think cories are super overrated... I got 6 pandas for my tank at the recommendation of almost everyone on here lol . I just personally don't like them, they don't do anything for me, not very active and honestly not very schooly. Just my personal opinion

Really? I just got two of them last night and I am OBSESSED. They follow each other around and dig through the sand, I think they have a ton of personality already. But to each their own.
(yes, I know I need more, I bought all I could find)

I wonder if I got a bad batch, they filter occasionally ( I know they are more nocturnal so they may to this more at night) but for the most part they sit in one spot, scattered around the tank, they don't seem to notice or care that there are others of the same kind around.
 
Guppies. They are so tempting and look so pretty. All research I did on them said they were hardy and perfect beginner fish. I got 5, 4 females and 1 male. Two died in the first week. The other 3 lived for about 6 months before dying. They never looked healthy though. I got 3 more (all males) for another tank from a different shop hoping I'd just got a bad batch but they died within a month. In both cases parameters were perfect, tanks were well established and all other tank mates were healthy and thriving. So difficult not to buy them again though since they are so pretty.

I also don't like males of a lot of fish. I really don't like male livebearers. I've got 6 female platies currently and I love platies. I had 1 male and 4 females and he harassed 2 of them constantly, he didn't spread it out between the fenales like he's supposed to do. I separated him to his own tank. But the main reason I don't like males is because they are usually a lot thinner. I don't like thin fish. They always look slightly unhealthy to me. This is mostly referring to livebearers and goldfish.

Hmm.. that's strange.

In general terms, if a large fish is contained in space too small, they will constantly seek a way out. For instance, musky (muskellunge) and pike have been documented to escape lakes and other impoundments that are too small. It’s been observed that these fish will seek an outflow and even attempt to jump over a spillway to get out.

Some of these monster fish that are kept have very little documentation/research in terms of home range, behavior, etc too.

Finally, from my perspective, “monster fish” isn’t just about how big it gets (length/weight). IE Shad and herring not necessarily get “monster fish” size but are generally pelagic, anadromous fish not suited to captivity.


These are just my opinions and not meant to be critical/judgemental of anyone keeping monster fish.

That is because you got the bare minimum.
 
My least favourite fish was the guppy. At the time I didnt like the quality of pet store guppies, even if they were hardy, there was no care for form, coloration or even variety. However, since becoming passionate about 'show' quality guppies, therefore line bred, they become a new interest for me. Which explains why I have a couple of pairs of albino koi guppies being shipped to me....

All down, my least favourite fish would either be the serpae tetra - for me, those things were little flap flaps filled with rage - or the platy/swordtail/molly.

Theres loads out there, an quite a interesting selection make great colourful community fish.
 
Goldfish. I use to have them and they were always sick.
1000 ... Congratulations Dawn
It's my honor to have given you your 1000th rating.

I disagree. It definitely depends on the fish though. What fish are you referring to specifically? (Lets keep it civil, We break it up if this is going no wheres)
 
I can't think of any fish I have kept that I didn't like... Which isn't many, but that I haven't kept I don't like glofish,
 
I don’t mind glofish as fish, but I swear I get a headache every time I look at the display with the black gravel and the color-changing light and the glowy anemone thingy and so forth. I mean, with a less aggressive background they’d be fine.
Fancy goldfish I don’t like, though. That little hunched-up body is just so sad. And I’m not particularly fond of albino fish; they don’t look interesting to me. Nothing against the fish itself in either case.
