Things to ponder

Fish tanks are for fishes, not decorations. Keep the deco at a minimum, your fishies will be safer and happier that way!

Once your bio-media is on track and your tank is established, don't go poking around too much! The tank will mini-cycle every time. Don't fix what's not broken!

Don't remove too much gravel at one time - bad.. bad idea! You will go through a mini-cycle blip if you do, instead remove a handful or too with each water change.
