Do I need to do anything special

[WhispTech]

Was wondering if I have to do anything special for my plants in a 3 gallon tank or will they be ok.

They'll probably be ok with enough lighting. Adding any special nutrients will probably be an overdose and may harm things.

What about all these co2 or whatever injection kits these guys in the froum are talking about for their plants?

Is that because they have huge tanks?

I wouldn't try co2 in anything less than 10 gallons. Remember fish breathe out co2, and plants take in co2. In such a small volume of water, if you have live plants then the co2 the fish provide will be enough.

CO2 is, after light, the next most limiting plant nutrient. Supplementing with CO2 is most beneficial with good lighting.

I would not consider adding CO2 to such a small tank though.
