As with the fish, feeding can be done either daily or every other day. Treats, such as live or frozen brine shrimp or tubiflex worms, can be purchased at a local pet store but be very cautious to feed only tiny amounts to avoid polluting their home. What you purchase can be frozen, used at later times and will probably be enough to last for many months. You will know that your are over-feeding if the water gets cloudy or you see food floating around more than five or ten minutes. If you overfeed consistently, you will need to change the water more often or your fish and plants may die.
Fish always look hungry.
Use only bottled spring water at room temperature for your aquarium. First remove the plant and set aside, then carefully pour the water into a bowl, using a cup to catch the water with the fish. Once the fish are out, discard the rest of the water, being careful to save the rocks. Rinse the rocks with the spring water until clean and use a paper towel to gently wipe down the sides to remove any algae. Add some new water and the cleaned rocks and anchor the plant end under some rocks.
