How many guppies can be kept in a 2 gallon fish tank?

I intend to get a cheap 2 gallon fish tank to hold some guppies over the winter and that is the reason for the question.

I expect to try and get the guppies out by the end of September and put them back in May.

to the guy who said 30 or more, you should be slapped.

2-3 guppies tops, i wouldnt even put them in a 2 gallon, that would make a nice home for a single beta. smaller the fish tank, the more the upkeep.

Need a supplier of large-scale aquarium supplies?

Hey, I’m in the market for a large aquarium and need to find a place to buy it and supplies to go along with it. I’m thinking of a 300 gallon, and yes, I do know what I’m doing. I just have no clue where I can acquire a tank this large or where I can find the heaters, filters, etc. for it.
Any help is appreciated, thanks!

No. A rainbow shark will quite quickly outgrow a 10 gallon tank.

My dad dumbed almost 1000 unwashed pennies in our aquarium tank, is this ok, willl the fish be alright?

There are almost 1000 pennies in the aquarium, all unwashed and who knows where they been. My dad dumped it in the aquarium tank as decorations, and it looks amazing, especially with the gold fish. The question is, can they die out or get sick or some kind of disease because no-one knows where those pennies were. You never know meaby someone took a dump and touched those pennies with unwashed hands. Does anyone know the answer to this?

I think you are at risk for this turning into a disaster. It is going to change the pH of the water… If you read the source below… I think you might start to get an idea of the impact it could have. I am sure you will get some input from some corrosive experts. If it were saltwater it would really be deadly.
This is a really bad idea… but it might take some time to be fatal… it will be an agonizing neurotoxic death that will not be recoverable once the signs/symptoms start from the copper salts. Copper sulfate is used in pesticides. Click on the "copper toxicity" paragraph… it give the lethality formula

Is a saltwater aquarium a lot harder to maintain than a freshwater?

I have a freshwater aquarium (10 gallon), and it’s nice and all, but I’d like to try an aquarium with some really beautiful fish. A lot of the colorful ones are saltwater. I take care of my tank, and it’s not a big hassle. I change the water, add some chemicals, feed them, make sure everything is ok every day, and that’s about it. Is a saltwater tank significantly harder to maintain? And besides for what I just mentioned I do to take care of my freshwater tank, what additional things do I need to do to support a healthy saltwater tank?

Or would you recommend just buying a bigger tank and purchasing aggressive fish? Those seem to be really nice too. I was thinking cichlids and some others, maybe an eel too. Can peaceful fish such as my australian rainbow be put in with fish like those? Thanks, any ideas/help/comments would be appreciated.
In answer to how much I want to spend, not too much, but I don’t have a set limit. I want to make sure I get good equipment. The size I’m planning for is 55 gal. Is that a good size that will allow me some diverse fish, or is that too small? Also, as someone mentioned the lighting, is that for the coral etc., or fish? In my current freshwater tank I rarely have the lights on.

-Fill a tank with salt water ( specific garvity should be around 1.021 – 1.025 and a new filter (you need somthing that moves at least 10 gallons/hour for every gallon of salt water. Use only Reverse Osmosis cleaned water, regular water (even dechlorinated) will cause huge slime and algae blooms.
-Add a few inches of crushed aragonite, shells or sand
-Add at least 10 pounds of live rock (cured is best, you can tell if it isn’t if it has a stong smell) for about a 40 gallon tank
- You will need to have floescent lights (one floescent and one actinic tube is better and you channge one every six months so that niether is ever more then one year old)
- A heater is probably a good idea depending on what fish you have
- Test the water daily, Like a freshwater tank the ammonia nitrite and nitrate levels will all take a turn at rising, then subside to normal levels. When the levels are no longer spiking, it is time to start slowly adding fish. This can take a few months to a year – depending on how lucky you are.
- Maintaining a fish-only tank isn’t too hard once it is started. You do weekly salt-water changes of about 10% of the water, and replace evaporated water with water only (salt doesn’t evaporate). Feed whatever is appropriate to the fish in the tank. Other then mixing the salt water, it is as much work for me as my tropical tanks.
- Corals are what makes it a huge expense and challenge as they need metal halide lights, skimmers, refugiums, chillers etc. not too mention the supplements and feeds.

How important is aquarium salt for a freshwater aquarium?

I just bought a new fish tank that I’m filling with freshwater fish tomorrow, but I need to know if its absolutely necessary to have a canister of aquarium salt in there. Petco does it. I’ve never seen it done before so what, if any, are the benefits?

Unless you are keeping certain species or treating for certain diseases, there is no reason to have salt in the water.

Most fish don’t need it and some are very sensitive to it and it will actually harm them.

By the way, before you fill up a tank and ‘fill it with fish’, I would highly recommend that you read this:

It may save you the trouble of coming back here in three days to ask "Why did all my fish die?"

How do touch pools at aquariums work?

I keep fish as a hobby, and you learn to not touch the fish if you can avoid it so you don’t introduce things into the water. I know you have to watch salt water chemical levels closely, and salt water creatures seem more delicate. How do the large aquariums make touch pools work? Who knows what are on the kids hands when they touch the sea creatures… Is it constant water changes? Do they switch the sea creatures frequently so the don’t stress out and get sick?

at ours we change the water constantly
