Aquarium Advice Newbie
I just bought my first aquarium. It's a 29 gallon with a Penguin 200 filter. I've got gravel, two fake plants (need more) and a few rocks that I found in a mountain creek. Tuesday I put 4 small tiger barbs in there and am currently cycling the tank with them. The tiger barbs have been in there for 3 days and are getting more comfortable with their surroundings now. I need to put a solid background on there and add some more cover for them.
My concern/question is about the rocks. The more I look at them I'm worried that there is rust on them. Initially I just thought it was a neat orangish color but now I'm not sure. Do other people also think it's rust? If it is rust, will the rust be bad for the fish? The three pictures below show one of the three rocks that I'm concerned about. The other two rocks in the middle picture I think are okay. They don't have any of the orange color on them.
