Ahhh. I want real plants soo bad. But I know much about them (I think!).
For the gravel, you're going to need a fertilized substrate. I would recomend
Eco-Complete Plant Substrate from Doctor's Foster & Smith. I LOVE that online store!
You're going to need CO2. Fish supply CO2, but sometimes that's not enough, or it is enough but becomes depleted soon, causing the aquarium plants growth to become stunted (Right? Not sure about that...) Since you're aquarium is small, you could get a small CO2 infiltration system, or you could get tabs that will induce CO2. I forget the product name, but I will find it.
Check your water parameters. Certain plants thrive in certain water conditions.
Full spectrum lighting at least 12 hours per day
Temperature should be between 75-88° Fahrenheit
pH between 6.5-7.4
Five degrees KH
Eight degrees GH
CO2 levels as high as possible, but lower than 40 mg
Low to zero surface turbulence to help retain CO2
25% water changes every other week
Appropriate substrate for root growth
Plants... Plants...
Get a good hardy selection of plants. I really like this website:
LiveAquaria It's another website from Doctor's Foster & Smith. I don't shop on there, their shipping is excruciatingly expensive, but when you click on the plant, there is info on the water parameters, hardiness, carelevels, etc.
Plants like Anubias, Anachiris, Microsword, Wisteria, Temple-Narrow leaf, Four Leaf Clover, and Java Fern are good starter plants. Add some colour of reds! Get some drift wood, too!
Lighting... It still confuses me.
xd You'll need a good ammount of wattage, and probably lighting around the 6700K on the spectrum (I'm still confused about this, sorry!!) I don't really understand this part.
Also: Be sure to have fish that go well with your plants! Some enjoy eating/uprooting and destroying plants! I tried plants once, but a couple of the fish I had ate them! Gr!
I hope you have success! And I don't know if Petsmart sells them. I don't have that around here, and I don't shop at chain petstores
razz They're usually uninformed and little help.
