What kind of fish should I put in my tank?

I currently have a 1.66 gallon tank that is empty in my apartment. I used to have a betta but after a year he died. I've cleaned the tank out, and am now looking for something to put in it. It sits away from any direct sunlight and it has an undergravel filter. Any suggestions?It's a freshwater tank.

Goldfish

do you have a saltwater tank or a freshwater tank? that makes all the difference.

most petstores if you ask them have goldfish in the back that are like 10 cents each! i kept a goldfish alive for 5 years once so i no they will last with good care

The aquatic ones. Don't, do not; ever, buy those big ones with four legs and ears. Don't believe them when they say that they're a new breed.. Yes, we know a chicken when we see one.

I have had three betta fish. I think they're perfect:they're pretty, and dont require much maintenince. You can buy them at Pets Mart or even wal-mart.

DEPENDS ON HOW MUCH TIME YOU HAVE TO CLEAN YOUR TANK(FOR EXAMPLE GOLD FISH YOU CAN BUY A SMALL ONE ) THEY ARE FUN TO WATCH GROW INTO A LARGE ONE;BUT IN THE OTHE YOU WOULLD HAVE TO CLEAN THE TANK 1-2 TIMES PER WEEK THEY ARE EXTREMELY SLIMELY FISH AND THE WASTE THEY PUT FROM THIER BODIES MAKES FOR A REALLY DIERTY TANK;TROPICAL FISH TAKES LES TIME AND CLEANING ;HAVE YOUR WATER TESTED TO SEE WHICH TROPICAL BREED IS BEST FOR YOUR WATER

Tropical freshwater fish from South America are colourful and entertaining as well as cheap. A good pet shop that specialises in aquaria will help - try to vary species to bottom feeders as well as mid level and upper level dwellers, that way there will always be a number of fish swimming about and not just hiding under or behind a rock

Fantail goldfish

goldfish. tetras. if you want a bunch of fish, get two guppies and youre set for life. koi? go to walmart or a petstore and see what kinds you like.

Any thing that is freshwater fish. Just limit it to one or two. They have to have room to grow and move around. Goldfish are easy and so are guppies.

1.66 gallons is too small for anything other then a betta. Try getting a different tail type if you don't want something that looked the same as your last one.And to the stupid people that suggest a goldfish, can you please not give bad advice. They are looking for help not a way to kill some helpless animal. Goldfish can grow to around 8 inches or more and can live for 20+ years.

The only thing I would suggest for a tank that small is a betta. You can only have 1 fish in a tank that size.Definitely don't get a goldfish. I had a goldfish starter kit (5 gallon), I quickly had to upgrade to a 20 gallon tank. Goldfish are too big and messy for a tank that small.

I suggest the smaller type of goldfish. I suggest you feed them goldfish flakes. Probably four or five in your current tank.

Try making it into a water garden with aquatic plants in it , or keep it as gravel, plants, snails and such. Maybe a moss garden? Or keeping invertibrates and crayfish/frogs and stuff like that instead. if you're dying for a fish, get a betta.

The best fish for a small tank set up will always be the goldfish. They come in a suprising variety, can survive harsh conditions (and even some neglect, God forbid!), and are honestly dumb enough that they can swim around the tank a million times and its still new to them. They're naturally happy all the time. Goldfish can also be very attractive, and if you give them special food, their colors become even more brilliant.

A betta. Even then you'd be squeesing it. A goldfish gets well over 2 feet. God, I hate animal cruelty, and in such numbers. A 2 foot fish goes into the 1.5 gallon. I though the inch per gallon rule was bad but this? ShockingGet something bigger then you'll have a nice choice.

mostly live but a few dead wont hurt

Definitely NOT goldfish! That tank is WAY too small for a goldfish to live a healthy lifestyle!First thing you need to do is cycle your tank. After the cycling process is complete, you can think about fish. See the following link for great information about cycling your tank: http://www.flippersandfins.net/Cycling.htmA general rule of thumb is an inch of fish per gallon. Since you have such a small tank, your best bet would probably be another male betta. Most of your other choices will either be schooling fish (and there just isn't any room to school in there) or they'll outgrow it too quickly.I hope this helps. Good luck with your new tank.

The drawback is that you don't have a heater. You would need fish that can stand room temperature water. And a fish that is small. (general guideline is 1" of fish per 1 gal of water) Only I can think of is a beta or goldfish. There is a fish called a shebunkin. They look sorta like a koi, but they stay small like a goldfish. They're calico usually like a cat.. multi colored. They're actually kinda neat looking.
