We're a pretty good community here - no one wants to be unkind, we only want to help By people saying you're overstocked, they're letting you know that there are too many fish in the tank, they don't mean it in an unkind way at all. Overstocking has happened to many beginners, myself included.
Hmm, you could add a different smaller gravel, and then have a few of the nice stones as decoration on top? When you have a lot of fish, being able to clean well is important Do you use a gravel vaccum, like a siphon?
Plants are generally good to have, but I think in this case you have enough plants. If you have more, there will be less room for the fish to swim.
I've merged your posts since they were back to back. Don't forget there is an EDIT key at the bottom of every post that you can use for corrections or additional thoughts. It helps to save a little space on the forum.
Please keep a watch on the fishes for initial couple of weeks since the tank is new and perhaps not cycled. If you see any signs of fish getting stressed, you would be required to add beneficial bacteria.
THE REASON UR TANK ONLY TOOK 4 DAYS TO CYCLE IS BECAUSE OF THE SIZE, you have a very nice tank its pretty, And not meaning 2 be negative but a overstocked tank will only end in disaster and that very pretty tank of yours will become very much the oppisite the water will be very hard to keep clear and algee green and brown plus waste products will build up fast on the tank floor.. Im sorry please dont take this bad im just trying to help you. if you wish to maintain the look and health of your tank and fish please o please rethink ur stocking.
