i hav a 2ft by 1ft aquarium.suggest me any gud fish for dat!?

Answer 1

2 feet by 1 feet is only about 15 gallons, so your options are limited to some tetras and a small centre piece fish.

For a centrepiece fish, either:
One dwarf gourami, or
One male betta, or
Two kribensis cichlids

For your school of tetras, you could go with any small tetras, just as:

cardinal tetra http://www.thetropicaltank.co.uk/Fishindx/Fishpics/cardinals.jpg
lemon tetra http://www.aqua-fish.net/imgs/fish/034.jpg
harlequin rasbora http://tropicalresources.net/phpBB2/templates/BMan1Blue/images/profile_pics/fish_profiles_heteromorpha1.jpg
glowlight tetra http://www.solodvds.com/images/fish/Hemigrammus_erythrozonus_s.jpg
zebra danio http://www.winternet.com/~mchristi/fish/zebradanio.jpg
Get 6-8 of one of those types.

Then throw in a mystery snail, and voila.

Have you cycled your tank? In the wild, and in established tanks, there are nitrifying bacteria that break down toxic ammonia from fish waste and excess food into less toxic nitrates. In a brand new tank, these bacteria don't exist, so any fish in the tank will produce ammonia, which, not being broken down by bacteria, will kill or weaken the fish. So, it is vital to cycle your tank.
There are a few methods. Do you have access to an established tank? These bacteria live in the gravel and in the filter cartridge, so if you can get some from another tank, you can put the bacteria right into your tank (don't let the gravel or filter cartridge dry out). If you do this, in a day or two, your tank will beready for fish.
Another way is to get Bio-Spira. It is the actual live bacteria in a little pouch, and your tank will instantly be ready for fish. http://fishstoretn.com/bio_spira.html

Other methods, which include putting a source of ammonia in the tank and letting the bacteria build up on its own, or putting a fish in and letting the fish produce ammonia (which borders on animal cruelty, because the fish will suffer from the ammonia in the tank), take 2 to 6 weeks before your tank is ready. If you rush that, any fish you buy may die, so try one of the instant methods I mentioned above (bio-spira or gravel from another tank)

Answer 2

it would be a little crowded so you would have to clean more often but in 10 gallons (sounds like what you have) you could put in a couple dwarf gouramies, angelfish or rainbowfish, a school (about 6) of tetras or rasboras (my personal faves) or danios -- 3 cory cats (they like working in groups and are a lot more lively that way). or 2 schools and no large fish -- maybe a school of barbs. or divide the tank into 1/4s and put in 4 male bettas. goldfish are a pain to keep in 10 gallons. you will be cleaning constantly.

Answer 3

A beta, a couple of goldfish, or a few tetras. It won't take much to overcrowd, so be careful.
