im starting a new 10 gallon tank especially designated for corydoras, i need to get small size gravel, plants (any ideas, java fern, swords, etc..), and i would like a big piece of wood or stick, you know you see that in a lot of tanks, should i use sponge or regular filter? i dont know but does anyone know a good site for plants or that wood. plus landscaping ideas. Dont worry im not a beginner i have been a succesful fish keeper for over 2 years, love cories, and have done all the research imagineable, and yes i have owned and currently own cories. i just never had a tank especially designed for them.
