What kind of fish do you have? I have bettas, so I only use silk plants with them. I have the Sea Garden Curly Crispus plants. They look very nice, but they have a bit of a brownish color to them. I also have some base plants from Imagine, and they are a much darker green. The base plants don't really match the curly crispus (but that will not matter to the fish!) But I am kind of looking for base plants that will match the crispus a little better. I also have a few Penn Plax silk plants that I also like, but can't find anymore.
P.S. If I remember correctly, the crispus had a pointy, white plastic flower in the leaves. I cut this part off so it wouldn't hurt the betta.
